7a2aa8b681 OMAP3 Move cache routine to cache.S
v7_flush_dcache_all, because it depends on omap ROM code is not
generic.  Rename the function to 'invalidate_dcache' and move it
to the omap cpu directory.

Collect the other omap cache routines l2_cache_enable and
l2_cache_disable with invalide_dcache into cache.S.  This
means removing the old cache.c file that contained l2_cache_enable
and l2_cache_disable.

The conversion from cache.c to cache.S was done most through
disassembling the uboot binary.  The only significant change was
to change the comparision for the return of get_cpu_rev from

   cmp	r0, #0
   beq	earlier_than_label

Which was lost information to

   cmp	r0, #CPU_3XX_ES20
   blt	earlier_than_label

The paths through the enable routine were verified by
adding an infinite loop and seeing the hang.  Then
removing the infinite loop and seeing it continue.

The disable routine is similar enough that it was not
tested with this method.

Run tested by cold booting from nand on beagle and zoom1.
Compile tested on MAKEALL arm.

b54384e3ba arm: timer and interrupt init rework
actually the timer init use the interrupt_init as init callback
which make the interrupt and timer implementation difficult to follow

so now rename it as int timer_init(void) and use interrupt_init for interrupt

btw also remane the corresponding file to the functionnality implemented

as ixp arch implement two timer - one based on interrupt - so all the timer
related code is moved to timer.c
