CLKDEV: provide helpers for common clock framework
The common clock framework allocates clocks dynamically.  Provide a
set of helpers to streamline the clkdev registration of the clock
lookups to avoid repetitive code sequences.

ARM: 7392/1: CLKDEV: Optimize clk_find()
clk_find must return as soon as it gets the correct clock. Currently it check
all clocks until it found a lookup with both dev_id and con_id matching.

If only one of them is passed, then we don't actually need to wait for both of
them to match. We can quit as soon as the requested id (dev_id or con_id)
matches.

CLKDEV: Fix clkdev return value for NULL clk case
clkdev may incorrectly cause a clkdev entry with a NULL clk to return
-ENOENT.  This is not the intention of this code; -ENOENT should only
be returned if the clock entry can not be found in the table.  Fix
this.

ARM: 6483/1: arm & sh: factorised duplicated clkdev.c
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
