Rather than marking the mach/gpio.h header files which want to use the
trivial GPIOLIB implementation, mark those which do not want to use it
instead. This means that by default, you get the trivial implementation
and only have to do something extra if you need to. This should
encourage the use of the trivial default implementation.
As an additional bonus, several gpio.h header files become empty.

Many of the gpio_to_irq implementations use the gpiolib version of this
function. Provide the standard gpiolib gpio_to_irq() for everyone, but
allow platforms to override it if they wish. Add the neccessary
overrides for those platforms which do not use the standard definition.

Consolidate 24 trivial gpiolib implementions out of mach/gpio.h
into asm/gpio.h. This is basically the include of asm-generic/gpio.h
and the definition of gpio_get_value, gpio_set_value, and gpio_cansleep
as described in Documentation/gpio.txt

This fixes a regression introduced by e59347a "arm: orion:
Use generic irq chip".
Depending on the device, interrupts acknowledgement is done by setting
or by clearing a dedicated register. Replace irq_gc_ack() with some
{set,clr}_bit variants allows to handle both cases.
Note that this patch affects the following SoCs: Davinci, Samsung and
Orion. Except for this last, the change is minor: irq_gc_ack() is just
renamed into irq_gc_ack_set_bit().
For the Orion SoCs, the edge GPIO interrupts support is currently
broken. irq_gc_ack() try to acknowledge a such interrupt by setting
the corresponding cause register bit. The Orion GPIO device expect the
opposite. To fix this issue, the irq_gc_ack_clr_bit() variant is used.
Tested on Network Space v2.

The core interrupt chip is a straight forward conversion. The gpio
chip is implemented with two instances of the irq_chip_type which can
be switched with the irq_set_type function. That allows us to use the
generic callbacks and avoids the conditionals in them.

This patch makes the various mach dirs that use the plat-orion GPIO
code pass in GPIO-related platform info (GPIO controller base address,
secondary base IRQ number, etc) explicitly, instead of having
plat-orion get those values by including a mach dir include file --
the latter mechanism is problematic if you want to support multiple
ARM platforms in the same kernel image.

Commit 21f0ba90a447 "orion/kirkwood: reset PCIe unit on boot" made the
reset of the PCIe unit unconditional. While this may fix problems on some
targets, this also causes problems on other targets.
Saeed Bishara <saeed@marvell.com> said about the original problem: "We
couln't pinpoint the root cause of this issue, actually we failed to
reproduce that issue."
So let's restrict the reset of the PCIe unit only to the target where
the original problem was observed.

Patch found in QNAPs vendor source package, with some cleanups
(proper defines, shortened max. timeout from 1s to 200ms).
Without this patch the PCIe SATA controller (Marvell 88sx7042/sata_mv)
in my QNAP TS-419P (Marvell 88f6281/Kirkwood) stops working after a
few minutes.
The symptomes are described in this thread:

With a TCLK = 200MHz, the half period of the hardware timer is roughly
10 seconds. Because cnt32_to_63() must be called at least once per
half period of the base hardware counter, it is a bit risky to rely
solely on scheduling to generate frequent enough calls. Let's use a
kernel timer to ensure this.

Symbols like SOFT_RESET are way too generic to be exported at large.
To avoid this, let's move the mbus bridge register defines into a
separate file and include it where needed. This affects mach-kirkwood,
mach-loki, mach-mv78xx0 and mach-orion5x simultaneously as they all
share code in plat-orion which relies on those defines.
Some other defines have been moved to narrower scopes, or simply deleted
when they had no user.
This fixes compilation problem with mpt2sas on the above listed
platforms.

The GPIO interrupts can be configured as either level triggered or edge
triggered, with a default of level triggered. When an edge triggered
interrupt is requested, the gpio_irq_set_type method is called which
currently switches the given IRQ descriptor between two struct irq_chip
instances: orion_gpio_irq_level_chip and orion_gpio_irq_edge_chip. This
happens via __setup_irq() which also calls irq_chip_set_defaults() to
assign default methods to uninitialized ones. The problem is that
irq_chip_set_defaults() is called before the irq_chip reference is
switched, leaving the new irq_chip (orion_gpio_irq_edge_chip in this
case) with uninitialized methods such as chip->startup() causing a kernel
oops.
Many solutions are possible, such as making irq_chip_set_defaults() global
and calling it from gpio_irq_set_type(), or calling __irq_set_trigger()
before irq_chip_set_defaults() in __setup_irq(). But those require
modifications to the generic IRQ code which might have adverse effect on
other architectures, and that would still be a fragile arrangement.
Manually copying the missing methods from within gpio_irq_set_type()
would be really ugly and it would break again the day new methods with
automatic defaults are added.
A better solution is to have a single irq_chip instance which can deal
with both edge and level triggered interrupts. It is also a good idea
to switch the IRQ handler instead, as the edge IRQ handler allows for
one edge IRQ event to be queued as the IRQ is actually masked only when
that second IRQ is received, at which point the hardware can queue an
additional IRQ event, making edge triggered interrupts a bit more
reliable.
