mb/google/zork: Add support for active low wifi power enable
A late change went into v3+ of reference schematics which inverted
EN_PWR_WIFI to meet PCIe reset/power timings for WiFi device. This is
incorporated into v3.51+ for Trembyle reference and v3.2+ for Dalboz
reference. However, some variants are built with v3+ reference
schematics, but without the inversion of EN_PWR_WIFI polarity. Thus,
we need to add support for following combinations:
1. Pre-v3 Schematics
2. V3+ Schematics
3. V3+ Schematics + Active low wifi power
This change adds a new Kconfig
`VARIANT_MIN_BOARD_ID_WIFI_POWER_ACTIVE_LOW` that sets the minimum
board ID that has EN_PWR_WIFI active low in hardware. Variants that
missed this change in V3+ integration (berknip and vilboz) have board
IDs set to VARIANT_MIN_BOARD_ID_V3_SCHEMATICS + 1. For others, this
defaults to VARIANT_MIN_BOARD_ID_V3_SCHEMATICS.
