soc/amd/cezanne & picasso: Add Kconfig for hardcoded Soft Fuse bits
Currently, some of the PSP Soft Fuse bits are hardcoded in the Cezanne
and Picasso makefiles.
This makes it impossible for platforms to change them. This change puts
the hardcoded bits in Kconfig, allowing them to be modified by the
platform.
BUG=b:185514903
TEST=Verify that the correct Soft Fuse bits are set.
