[Tim Wawrzynczak (Code Review)]

Hello Paul Fagerburg, Philip Chen, Shelley Chen, build bot (Jenkins), Furquan Shaikh, Patrick Georgi, Martin Roth,

mb/google/hatch: Refactor override_early_gpio_table

There was the potential for misuse of the override early GPIO table,
because if the override early GPIO table did not have a corresponding
entry in the base table, it would not get overridden, and there was
no way to know except manual inspection (this has already happened
here), so now all hatch mainboards are required to explicitly list out
all of their required early GPIOs.

TEST=booted several hatch boards, verified that they can communicate
with TPM and successfully train memory
