lib/cbfs: Add CBFS_CACHE_ALIGN Kconfig option
This option will allow platforms to set the alignment of the cbfs_cache
buffers.
BUG=b:179699789
TEST=gdb -ex 'p cbfs_cache' /tmp/coreboot/guybrush/cbfs/fallback/ramstage.debug
$1 = {buf = 0x0, size = 0, alignment = 8, last_alloc = 0x0, second_to_last_alloc = 0x0, free_offset = 0}
