soc/amd/common/block/lpc: Set CBFS_CACHE_ALIGN to 64 when using SPI DMA
AMD platforms require the destination buffer to be 64 byte aligned
when using the SPI DMA controller.
BUG=b:179699789
TEST=gdb -ex 'p cbfs_cache' /tmp/coreboot/guybrush/cbfs/fallback/ramstage.debug
$1 = {buf = 0x0, size = 0, alignment = 64, last_alloc = 0x0, second_to_last_alloc = 0x0, free_offset = 0}
