Subject: [PATCH] gianfar: Use memset instead of cacheable_memzero
cacheable_memzero() is completely overkill for the clearing out the FCB
block which is only 8-bytes. The compiler should easily optimize this
with memset. Additionally, cacheable_memzero() only exists on ppc32 and
thus breaks builds of gianfar on ppc64.
