soc/amd/sabrina: Enable HW Modexp engine

HW Modexp engine is verified to be working fine. Any verification
failures during PSP verstage are because the firmware body is not read
correctly. This might be because of the incorrect SPI ROM mapping. Hence
enable the HW modexp engine for keyblock, preamble and firmware body
verification.

BUG=b:240175446
TEST=Build and boot to OS in Skyrim with PSP verstage using one of the
FW slots.
