mb/google/zork: Prepare variants for v3 schematics

This change updates variant_romstage_gpio_table() and
variant_wifi_romstage_gpio_table() to support v3 version of schematics
for dalboz and trembyle reference designs. gpio_set_stage_rom and
gpio_set_wifi are divided into two groups:
a) Pre-v3 (GPIO table for pre v3 schematics):
 * gpio_set_stage_rom_pre_v3
 * gpio_set_wifi_pre_v3
b) v3 (GPIO table for v3+ schematics):
 * gpio_set_stage_v3
 * gpio_set_wifi_v3

Currently, both _v3 is a copy of _pre_v3, but will be updated in
follow-up CLs to make it easier to identify what changed from _pre_v3
to _v3.
