soc/amd/picasso: Print values from PSP transfer buffer

The PSP will now pass us data on the PSP boot mode and the production
silicon level.  Print these values out to save in the log.

These definitions are in a vendorcode include directory that was
previously only included in verstage.  Add the include directory
to all stages.

BUG=b:170237834
TEST=Build & Boot - See values printed.
