Improve EEPROME load patches. Reorganize and rework them.
The current patch are bugged and with the case of MTD loading, leaks and
never free the EEPROM read values.
Also add support for loading EEPROM using NVMEM cells.
As a cleanup, change the binding to swap EEPROM read from mtd to
ralink,eeprom-swap and generilize it.

During the channel scanning process, the driver will continuously
switch channels. It seems that the full RF calibration step in
rt2800_config_channel() caused the channel scanning function to
timeout. To fix it, move the RF calibration to rt2800_enable_radio()
so that it is only executed once. This commit also includes some
coding format adjustments to follow the Linux recommended style.

This patch makes some improvements to the MT7620 RF calibration.
1. Move MT7620 PA/LNA calibration code to dedicated functions.
2. Restore RF and BBP registers before R-Calibration.
3. Do Rx DCOC calibration again before RXIQ calibration.
4. Use SoC specific AGC initial LNA value.
5. Correct MAC_RX_EN mask in rt2800_r_calibration()[1].
[1] This change may fix the "BBP/RF register access failed" error:
ieee80211 phy0: rt2800_wait_bbp_rf_ready: Error - BBP/RF register access failed, aborting
