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.
