soc/amd/mendocino: Enable x86 SHA accelerator

Enable x86 SHA accelerator for use by VBOOT library. This is useful when
CBFS verification verifies the hash of the file being loaded in x86.

BUG=b:227809919
TEST=Build and boot to OS in Skyrim. Observe a boot time improvement of
~10 ms with CBFS verification enabled.
