[PATCH] ARM: 2784/1: Fix the block cache flush operation range

Patch from Catalin Marinas

The range for the ARMv6 block cache operations is inclusive but the
kernel doesn't re-calculate the end address, causing a page fault when
used (this only happens with support for cache aliasing, otherwise the
blk_flush_kern_dcache_page() is not called). This patch subtracts
L1_CACHE_BYTES from the end address.
