mb/google/zork,soc/amd/psp_verstage: Add verstage_mb_{tpm/espi}_init
These functions can't be weak, because they actually need to configure
the GPIOs for eSPI and the TPM. With this change zork boots again.
I also noticed that zork doesn't use the early table in bootblock. This
means that zork will only boot if psp_verstage is enabled.
BUG=b:209465425
TEST=boot zork to ramstage
