Move chainmask to struct mt7615_phy and instead of needlessly making the
format similar to values for older chips, make it refer to the actual chain
bits used for the rx/tx path.
This is important for multiple wiphy support, where for a secondary phy,
antenna_mask will start at 0, and chainmask will start at the chain offset
(bit 2)

Some tests shows that using AMSDU to aggregate TCP ACKs to specific
APs will degrade the throughput on 2.4G band in 20MHz bandwidth
(< 10 Mbps, should be ~100 Mbps for 2x2). Also found that there's
barely no negative impact if we disable TX AMSDU on 2.4G to connect
to other APs. So it seems like we can just tell mac80211 to not to
aggregate MSDUs when transmitting on 2.4G band.

Note that we still can TX AMSDU on 5G band and benefit from it by
having 50 ~ 70 Mbps throughput improvement.

According to some experiments, the original RF register protection
setting of 8822c cannot perfectly make sure that there is no hardware
PI write (direct) during direct write. Modify the setting so that the
hardware block of PI would be turned off via rtw8822c_rstb_3wire()
during the direct write, to avoid RF register racing.

Note that 8822b uses SIPI write (indirect), so 8822b does not
have such problem.

Driver could possibly be dead-locked while canceling works with
*_sync() with mutex lock held. Those cancel_delayed_work_sync()
functions will wait until the work is done, but if we hold the
lock, they will never acquire the lock.

To prevent this, simply release the lock and acquire again after
the works have been canceled. And to avoid the works being queued
again, check if the device is at RTW_FLAG_RUNNING state, otherwise
just return and do nothing.

When driver is coming up, mac80211 will set changed as ~0 (0xffffffff),
and driver could enter IDLE state (power off) before switching channel or
other config event. So move rtw_enter_ips() to the last, to make sure the
driver completed the config events before going to IDLE state.

So, moves leave/enter IPS config to be first/last one according to flag
IEEE80211_CONF_IDLE. If there're more configureations we want to add in
the future, they must locate between leave/enter IPS.
