DIV_ROUND_CLOSEST() after kstrtoul() results in an overflow if a large
number such as 18446744073709551615 is provided by the user.
Fix it by reordering clamp_val() and DIV_ROUND_CLOSEST() operations.

According to IEEE P802.11be/D6.0 Table 9-417n, beamformee SS field stands
for the maximum number of spatial streams that the STA can receive in an
EHT sounding NDP minus 1, and the minimum value of this field is 3.
This value indicates the decoding capability of a beamformee, which is
independent of current antenna settings. Correct the value for mt7996
and mt7992 chipsets based on their HW capability.

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.
