FRV: ARCH_KMALLOC_MINALIGN was already defined

ARCH_KMALLOC_MINALIGN was already defined in asm/mem-layout.h and so shouldn't
have been added to asm/cache.h as well, but rather altered in place.

The commit that added it to asm/cache.h was:

commit 69dcf3db03626c4f18de624e8632454ea12ff260

frv: set ARCH_KMALLOC_MINALIGN

Architectures that handle DMA-non-coherent memory need to set
ARCH_KMALLOC_MINALIGN to make sure that kmalloc'ed buffer is
DMA-safe: the buffer doesn't share a cache with the others.
