Subject: [PATCH] mb/google/zork: Ensure eSPI GPIOs programmed w/o vboot

On the non-vboot boot path, eSPI is configured as part of
fch_pre_init(), and we need to ensure that the mainboard sets the
eSPI GPIOs properly before the common SoC code performs eSPI init.
Use the mb_set_up_early_espi() function to set the eSPI GPIOs at
the correct time.

TEST=build/boot google/zork (morphius), verify keyboard functional.
