MT7615 supports dual-wiphy which means that it can run on 2.4G and 5GHz
channels simultaneously, and driver should configure each band.
Add missing register settings, and refine band related definitions to
avoid duplicate codes.

There are two DFS detectors on the chip. When using 160 MHz channel bandwidth
(not supported in dual-wiphy mode), both are used. Otherwise, one detector is
used per wiphy.

radar event on the right phy based on the detector index

The hardware expects MT_TX_RATE_NSS to be filled with the number of
space/time streams. For non-STBC rates, this is equal to nss.
For 1-stream STBC, this needs to be set to 2.
This is relevant for VHT rates only, on HT, the value is derived from MCS
internally.

- Store the previous and current rate set in the driver + the TSF value
at the time of the switch.
- Use the tx status TSF value to determine which rate set needs to be used
as reference.
- Report only short or long GI rates for a single status event, not a mix.
- The hardware reports the last used rate index. Use it along with the
retry count to figure out what rate was used for the first attempt.
- Use the same retry count value for all rate slots to make this calculation
work.
- Derive the probe rate from the current rateset instead of the skb cb
- Do not wait for a status report for the probe frame before removing the
probe rate from the rate table. Do it immediately after it was referenced
in a tx status report.
- Use the first half of the first rate retry budget for the probe rate
in order to avoid using too many retries on that rate
- Switch from lower rates to higher rates more conservatively
- enable hardware rate up/down selection
