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.
BUG=b:157140753
TEST=Build trembyle and boot to OS
