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

Add a dummy clk definition for the APB pclk signal on all platforms
using the AMBA bus infrastructure.  This ensures that these platforms
continue to work when the core amba bus code controls the APB pclk.

This adjusts the clockrate for the MTU timer. On the different
UX500 variants this rate is different. The platform can also have
been set up at hardware initialization, bootloader or early init
for different clock speeds. To have the clock framework available
early so the timers can use them, the clock initialization for
Nomadik and ux500 is moved to IRQ init time. A custom per-clock
callback is added to handle special cases like this.

This solves a user-visible bug: without this patch the current
UX500 platforms will not be synchronized to wall-clock time and
the platform will drift in time.

Add clocks with appropriate names in platforms that use it, and use the
clk API in nomadik-gpio.

Add a table for clocks to be defined statically, so that new clocks can
be added without having to call nmdk_clk_create() for each of them.
Remove the now unused nmdk_clk_create() function.

This patch adds the basic infrastructure for the Nomadik 8815
CPU and the "Nomadik Hardware Kit" NHK8815. This patch only
includes the serial console and core stuff, no drivers.
