Since there're mulitple clock rates in some device controllers, enable
clk_set_rate() for this usage.

Replace sysdev classes and struct sys_device objects used for "core"
power management by the PXA platform code with struct syscore_ops
objects that are simpler.
This reduces the code size and the kernel memory footprint. It also
is necessary for removing sysdevs entirely from the kernel in the
future.

The core of PXA955 is PJ4. Add new PJ4 support. And add new macro
CONFIG_PXA95x.

factorise some generic infrastructure to assist looking up struct clks
for the ARM & SH architecture.
as the code is identical at 99%
put the arch specific code for allocation as example in asm/clkdev.h

Most machine classes want some way to register a block of clk_lookup
structures, and most do it by implementing a clks_register() type
function which walks an array, or by open-coding a loop.
Consolidate all this into clkdev_add_table().

clk_add_alias is commonly called for platform devices that are not yet
registered in the device tree. Thus the clock alias is associated with
NULL device name. Fix this by passing the device name instead of just
device pointer.

This patch allows dynamic creation of clock aliases in order to
make it possible to have platform independent clock names for use in
device drivers.

We need to support more than one name+device for a struct clk for a
small number of peripherals. We do this by re-using struct clk alias
to another struct clk - IOW, if we find that the entry we're using is
an alias, we return the aliased entry not the one we found.
