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
	Author: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
	Date:   Mon May 24 14:32:54 2010 -0700

	    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.
