msm7627A: Enable 7627A specific memcpy routine
Cache line size for 7627A is 32 bytes. The existing memcpy routine
gives sub-optimal performance for this cache line size. The memcpy
routine has been optimized taking this into consideration. Currently
7627A is the only ARM-v7 target with cache line size of 32 bytes,
hence this optimized code has been featurized under
CORTEX_CACHE_LINE_32 in memcpy.S, memset.S, which can be enabled
by definingTARGET_CORTEX_CACHE_LINE_32 in BoardConfig.mk
This change also adds corresponding cflag definition in Android.mk.
