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.
Rework the code to start/stop them separately per phy and to indicate the
radar event on the right phy based on the detector index

Add support for an extra wiphy in mt76_set_channel and mt76_get_survey
This is preparation for supporting multiple wiphys per device to support the
concurrent dual-band feature of MT7615D

- 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
