soc/amd/picasso: add psp_verstage
This is the main code for building coreboot's verstage as a userspace
application to run on the PSP. It does a minimal setup of hardware,
then runs verstage_main. It uses hardware hashing to increase the speed
and will directly reboot into recovery mode if there are any failures.
