This patch fixes the following TWT issues:
- Change table_mask to u16 to support up to 16 TWT stations
- Reject TWT flows for duplicated establishment
- Fix possible unaligned pointer
- Remove unsupported TWT_CONTROL_WAKE_DUR_UNIT flag
- The minimum TWT duration supported by mt7996 chipsets is 64. Reply
with TWT_SETUP_CMD_DICTATE if the min_twt_dur is smaller than 64

The connac3 removes fixed rate fields to reduce txd size and introduces
global rate tables (64 entries) for rate setting. Driver needs to fill
the corresponding idx in MT_TXD6_TX_RATE while tx, and push mt76_rate
into predifined table at bootup stage so that mvif->basic_rates_idx
can immediately switch out once setting changes.
spe_idx is also needed for fixed rate frames, and will be updated by
future patches.
Note that all table entries are shared across driver and firmware
(i.e.TxBF), hence adding MT7996_BASIC_RATES_TBL to reflect mapping
status.
