The function rt2800_iq_calibrate is intended for Rt5592 only.
Don't call it for MT7620 which has it's own calibration functions.

Subject: [PATCH] rt2x00: various experimental fixes for MT7620
Serge Vasilugin reports:
To improve mt7620 built-in wifi performance some changes:
1. Correct BW20/BW40 switching (see comments with mark see commets with mark (1))
2. Correct TX_SW_CFG1 MAC reg from v3 of vendor driver see
https://gitlab.com/dm38/padavan-ng/-/blob/master/trunk/proprietary/rt_wifi/rtpci/3.0.X.X/mt76x2/chips/rt6352.c#L531
3. Set bbp66 for all chains.
4. US_CYC_CNT init based on Programming guide, default value was 33 (pci),
set chipset bus clock with fallback to cpu clock/3.
5. Don't overwrite default values for mt7620.
6. Correct some typos.
7. Add support for external LNA:
a) RF and BBP regs never be corrected for this mode
b) eLNA is driven the same way as ePA with mt7620's pin PA
but vendor driver explicitly pin PA to gpio mode (for forrect calibration?)
so I'm not sure that request for pa_pin in dts-file will be enough
First 5 changes (really 2) improve performance for boards w/o eLNA/ePA.
Changes 7 add support for eLNA
Configuration w/o eLAN/ePA and with eLNA show results
tx/rx (from router point of view) for each stream:
35-40/30-35 Mbps for HT20
65-70/60-65 Mbps for HT40
Yes. Max results for 2T2R client is 140-145/135-140
with peaks 160/150, It correspond to mediatek driver results.
Boards with ePA untested.

If available, set chipset bus clock with fallback to cpu clock/3.

In order to carry out calibration on boards with ePA or eLNA the PA pin
needs to be switch to GPIO mode on MT7620. Implement that by selecting
pinctrl state "pa_gpio" which should be defined for MT7620 boards with
eLNA or ePA beside the "default" state.
