In contrast to mt76_wr() which we use to program registers,
on mt76_wr_copy() we should not change endian of the data.

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

When beacon length is not a multiple of 4, the beacon could be sent with
the last 1-3 bytes corrupted. The skb data is guaranteed to have enough
room for reading beyond the end, because it is always followed by
skb_shared_info, so rounding up is safe.
All other callers of mt76_wr_copy have multiple-of-4 length already.

We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.
