arch/x86/Makefile: Align VGA_BIOS to 64 bytes when using AMD LPC SPI DMA
AMD platforms require the SPI contents to be 64 byte aligned in order to use the SPI DMA controller. BUG=b:179699789 TEST=Build guybrush and verify cbfs was invoked with -a 64 Signed-off-by: Raul E Rangel <rrangel@chromium.org> Change-Id: I842c85288acd8f7ac99b127c94b1cf235e264ea2 Reviewed-on: https://review.coreboot.org/c/coreboot/+/56579 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Julius Werner <jwerner@chromium.org>
