The old cache coherency function names where wrong and misleading.
The new names are (purposely different from vendor manuals)
* commit_* (write-back only)
* discard_* (removing lines from cache only)
* commit_discard_* (write-back and removing lines from cache)
It's suspected the old names have led to wrong uses. The old names still exist
(as aliases) so every call via the old names need to be double checked and changed
to the new name.

Using BX has the effect to set the T bit, so it can return to a thumb
function
With this change, rockbox runs fine on Clipv2 built with -mthumb (for
most files which don't use inline 32 bits ARM assembly)
Some other places use code which change the T bit on armv5 but not on
armv4 so armv4 won't run

It is only used by gigabeats, and is defined in mmu-armv6.S already

clean_dcache and invalidate_dcache were incorrect and too tied to the
arm920t/arm922t 64-way set associative caches
Make those functions smaller on as3525, as this CPU has a smaller cache
than the gigabeat F/X
