security/vboot: Update build rules using x86 SHA extension
Currently build rules allow using x86 SHA extensions for all coreboot
stages when enabled. On some SoCs where verstage can run in non-x86
environment, x86 SHA extension cannot be used. Update build rules
accordingly such that x86 SHA extensions can be used in AMD SoCs. This
is particularly useful when CBFS verificiation is enabled which verifies
the hash of the CBFS file being loaded.
BUG=b:227809919
TEST=Build and boot to OS in Skyrim. Observe that hardware acceleration
is used when a CBFS file is loaded and observe an overall improvement of
10 ms.
