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.

And this is second v3 and still not fixed. The same as previous v3 and
previous v2 (???).
