mac80211: rt2x00: experimental improvements for MT7620 wifi

Serge Vasilugin reports:

To improve mt7620 built-in wifi performance some changes:
1. Correct BW20/BW40 switching (see comments 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.

driver. Previously, LED triggers had to be assigned to the netdev, which
was limited to a single VAP.

Move bbp_ready and rf_ready busy wait functions up in the code so they
can more easily be used. Allow specifying register mask in rf_ready
function which is useful for calibration routines which will be added
in follow-up commits.

From: Tomislav Požega <pozega.tomislav@gmail.com>
Add RXIQ calibration found in mtk driver. With old openwrt builds this
gets us ~8Mbps more of RX bandwidth (test with iPA/eLNA layout).

Instead of using the default value 33 (pci), set US_CYC_CNT init based
on Programming guide:
If available, set chipset bus clock with fallback to cpu clock/3.

Subject: [PATCH] rt2x00: add throughput LED trigger
This adds a (currently missing) throughput LED trigger for the rt2x00
driver. Previously, LED triggers had to be assigned to the netdev, which
was limited to a single VAP.

Stanislaw Gruszka <stf_xl@wp.pl>,
Helmut Schaa <helmut.schaa@googlemail.com>

Paolo Abeni <pabeni@redhat.com>,
Johannes Berg <johannes.berg@intel.com>
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.
