This patch fixes the jiffies wrapping bug in clock.c.
It corrects the timeout computation based on jiffies, uses time_before() for
correct wrapping handling and replaces a binary "&" which should really be a
logical "&&" in a truth expression.

This patch fixes the mutex issue in clock.c, as done in Kevin Wells' original
driver update:
In some cases, the clock drivers could grab a mutex twice in an improper
context. This patch changes the mutex mechanism to a simple irq lock/unlock
mechanism and removes un-needed locks from some functions.

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
