mb/google/zork: Add Picasso based Zork mainboard and variants

This is a copy of the mb/google/zork directory from the chromiumos
coreboot-zork branch. This was from commit 29308ac8606.

See https://chromium.googlesource.com/chromiumos/third_party/coreboot/+/29308ac8606/src/mainboard/google/zork

Changes:
* Minor changes to make the board build.
* Add bootblock.c.
* Modify romstage.c
* Removed the FSP_X configs from zork/Kconfig since they should be
  set in picasso/Kconfig. picasso/Kconfig doesn't currently define the
  binaries since they haven't been published. To get a working build
  a custom config that sets FSP_X_FILE is required.
