Add dt binding to get XO calibration data support for Wi-Fi RF clock.
Retrieve the XO trim offset via system firmware (e.g., device tree), especially in the case where the device doesn't have a useful EEPROM on which to store the calibrated XO offset. Calibrated XO offset is sent to firmware, which compensate the RF clock drift by programing the XO trim register.
