Commit 2f3427c added noop cache functions implementation for arm926ejs to fix compilation of drivers depending on these functions (DaVinci EMAC in particular).
Unfortunately, the bug was introduced: noop implementation calls dcache_disable which calls flush_dcache_all which in turn calls dcache_disable thus creating an infinite loop.
This patch removes noop implementation for flush_dcache_all, we already have default one in arch/arm/lib/cache.c and it should be used instead.

Hi Matthias,
thanks for cathing this. Surely my initial patch was totally wrong. Could you please test this one?
Regards, Ilya.
