mb/google/zork: Increase size of SMMSTORE to 512KB

Browse source 
Increase size of SMMSTORE FMAP region to 512KB to ensure a large
enough area is allocated to UEFI variable storage which allows for
variables (such as the UEFI revocation database) to be updated
via fwupd. Previously, such updates would fail with an error such as:
"efivar: No space left on device".
