rt2x00: Fix transmit power troubles on some Ralink RT30xx cards
Some cards on Ralink RT30xx chipset not have correctly TX_MIXER_GAIN
value in them EEPROM/EFUSE. In this case, we must use default value,
but always used EEPROM/EFUSE value. As result we have tranmitt power
range from -10dBm to +6dBm instead 0dBm to +16dBm.
Correctly value in EEPROM/EFUSE is one or more for RT3070 and two or
more for other RT30xx chips.
Tested on Canyon CNP-WF518N1 usb Wi-Fi dongle and Jorjin WN8020 usb
embedded Wi-Fi module.
