... in preparation for common clock coming for Integrator
and Versatile Express.
Based on Linus Walleij's "ARM: integrator: convert to common
clock" patch.

This does two things to the FPGA IRQ controller in the versatile
family:
- Convert to MULTI_IRQ_HANDLER so we can drop the entry macro
from the Integrator. The C IRQ handler was inspired from
arch/arm/common/vic.c, recent bug discovered in this handler was
accounted for.
- Convert to using IRQ domains so we can get rid of the NO_IRQ
mess and proceed with device tree and such stuff.
As part of the exercise, bump all the low IRQ numbers on the
Integrator PIC to start from 1 rather than 0, since IRQ 0 is
now NO_IRQ. The Linux IRQ numbers are thus entirely decoupled
from the hardware IRQ numbers in this controller.
I was unable to split this patch. The main reason is the half-done
conversion to device tree in Versatile.
Tested on Integrator/AP and Integrator/CP.

Now that we can select a sched_clock at runtime, let's implement
it for the Integrator AP, default-select the one found in all
other board it for all plat-versatile boards and make the right
clock kick in at runtime.

All sched_clock() providers have been converted to the sched_clock
framework, which also provides a jiffy based implementation for
the platforms that do not provide a counter.
It is now possible to make the sched_clock framework mandatory,
effectively preventing new platforms to add new sched_clock()
functions, which would be detrimental to the single zImage work.

Integrator/CP has the 24MHz counter which Versatile and later platforms
also have, which we use for sched_clock support. Allow this counter to
be used when building a kernel targetting Integrator/CP alone.
Integrator/AP does not have this counter, so we must exclude support
for the Integrator family when this is enabled.

Consolidate the FPGA IRQ handling code. Integrator/AP and Versatile
have one FPGA-based IRQ handler each. Integrator/CP has three.

Move leds and sched_clock build conditionals out of the Makefile into
the Kconfig file. Move selection of HAVE_SCHED_CLOCK into the
platform Kconfig rather than duplicating it three times in the main
architecture Kconfig.

This consolidates the CLCD panel definitions and memory allocation into
one location.
Rename the Sanyo 2.5in and Epson 2.2in displays after their respective
part numbers. Rather than using a general "Sanyo 2.5in" and "Epson
2.2in" description of the display panel, use the manufacturers part
number to be more specific. This helps people identify what the timings
actually refer to, which are panel specific.
While here, add CLCD capability information to each panel definition,
which has no effect until we add the board-level capabilities.
