Add REGULATORY_GAIN configuration to remain within regulatory ERP limit

Browse Source 
REGULATORY_GAIN is the total system gain in dBm to subtract from the configured Tx power, to remain within regulatory ERP limit for non-licensed operators.

This value should be set in variant.h and is PA gain + antenna gain (if system ships with an antenna).

This is similar to antenna_gain/NL80211_ATTR_WIPHY_ANTENNA_GAIN/NL80211_ATTR_REG_RULE_POWER_MAX_ANT_GAIN setting in Linux Regulatory/OpenWrt/mac80211/nl80211/iw.
