fe0f2de30c iwlwifi: mvm: Loosen the channel context/phy context coupling
In current implementation, the phy context is tightly coupled
with the channel context. This complicates the possibility of
using the same phy context for both netdev interfaces and the P2P
Device interface. To loosen this coupling:

1. Manage all the phy contexts in the mvm op mode, and only save
   the phy context id in the chanctx memory.
2. Reference count the phy contexts and free them only when they
   are not longer used (both by mac80211 and P2P Device).

5ee2b2154e iwlwifi: mvm: don't disable power management due to P2P device
Currently power management is supported only when only a single
virtual interface is present. The driver verifies number of created
interfaces and disables power management when multiple interfaces
present. However, this rule does not extend to a P2P device that is
handled differently in the firmware. If a P2P device is added power
management can remain enabled.

1e1391ca43 iwlwifi: mvm: Fix quota handling for monitor interface
1. Quota for the monitor interface should be added only if there is
   a channel context assigned to the interface.
2. In the unassign channel context flow, need to remove the quota
   for the monitor interface binding, before unbinding.

506a81e6ba iwlwifi: mvm: don't read system time when modifying AP/GO MAC
When modifying a MAC, we update its beacon system time which
is taken as a base to calculate TBTT. The firmware doesn't use
the new timestamp because the time is never used after the MAC
and broadcast station were added, but it is safer to not rely
on this and avoids the overhead of reading the register every
time the MAC is updated.

f444eb10d5 iwlwifi: fix wakeup status query and packet reporting
The wakeup packet in the status response is padded out
to a multiple of 4 bytes by the firmware for transfer
to the host, take that into account when checking the
length of the command.

Also, the reported wakeup packet includes the FCS but
the userspace API doesn't, so remove that. If it is a
data packet it is reported as an 802.3 packet but I
forgot to take into account and remove the encryption
head/tail, fix all of that as well.
