bc98f5bb6c Driver changes for FPGA SPI Tx LO control 
- Manually issue Tx Quadrature calibration if frequency change is more than 100MHz
- Disable FPGA SPI module before calibration
- Add xpu reg 13 to disable control manually

585a56016e openofdm_rx initialization with the help of macro definition in hw_def.h: 
Now changing the macro in hw_def.h will change the related initialization part in all related drivers (rx_intf/xpu/openofdm_rx)

0cbb687387 Change the default bb_gain from 290 to 250 in tx_intf: 
- 2022-03-04 detailed test result:
- - bb_gain 290 work for 11a/g all mcs
- - bb_gain 290 work for 11n mcs 1~7 (aggr and non aggr)
- - bb_gain 290 destroy  11n mcs 0 long (MTU 1500) tx pkt due to high PAPR (Peak to Average Power Ratio)
- - bb_gain 250 work for 11n mcs 0
So, a conservative bb_gain 250 should be used

469b96d342 Remove/modify the tx_intf register API according to the new FPGA: 
1. mixer/duc is not needed because we will not use offset tuning after the ad9361 tx lo control via FPGA is supported.
2. source selection register is not needed as well.
3. arbitrary IQ register is added.

72d992a6ec More correct hw flag set via ieee80211_hw_set to prevent: 
Some client, like iPhone, always has frequent PS (Power Saving) state change like this:
sdr0: STA e2:72:49:82:a6:a0 aid 1 enters power save mode
sdr0: STA e2:72:49:82:a6:a0 aid 1 exits power save mode
sdr0: STA e2:72:49:82:a6:a0 aid 1 sending 0 filtered/0 PS frames since STA woke up
Now with these correct hw flag setting, the link is more stable

7b2f8bdfff Align the inital actual_tx_lo/actual_rx_lo to rf_init_11n.sh: 
Make it far from our usual 2.4/5GHz to force ad9361 to calibration while up in 2.4/5GHz due to large tuning offset from the original frequency (1GHz)
