For WiFi 7 chips, we add H2C command with rich fields to support MLO, so
add a chip_ops to generalize calling of update CMAC table.

Many existing MAC access functions are used by WiFi 6 chips only, so add
suffix _ax to be clearer. Some are common and can be used by WiFi 7, so
export this kind of functions. This patch doesn't change logic at all.

Though WiFi 7 chips need BB MCU firmware, we don't download it in probe
stage. Instead, only bring interface up under normal operation or WoWLAN
mode. So, add an argument to assist download flow to setup download
settings properly.

rx_filter is used to decide which kind of packets are received to driver,
or just dropped by MAC layer to reduce bus traffic.
The bit definitions of old and new chips are the sames, but only address
is changed, so define a field to generalize usage.

Add WoWLAN stub to 8851B, and decalre this chip can support magic packet
and disconnect wakeup.

In WoWLAN Mode, it's expected that WiFi chip could enter power save mode
only after all setting is finished, but current wow_enter_lps function
break the rule and may lead to WoWLAN function fail in low probability,
so fix it.

We find that when starting WoWLAN, the second join_info H2C is
unnecessary and leads WoWLAN not enter power save mode if using new
firmware, so remove it.

The H2C of del_pkt_offload must be called before polling FW status
ready, otherwise the following downloading normal FW will fail.

For upcoming firmware, driver needs to do packet offload to firmware to
ensure LPS protocol work properly, so we update current connection and
disconnect flow to maintain packet offload flow, and integrate with
current WoWLAN flow which also needs packet offload.

'ret' is not updated after several function calls in rtw89_wow_enable().
This prevent error handling from working.
Add the missing assignments.

Pattern match is an option of WoWLAN to allow the device to be woken up
from suspend mode when receiving packets matched user-designed patterns.
The patterns are written into hardware via WoWLAN firmware in suspend
flow if users have set up them. If packets matched designed pattern are
received, WoWLAN firmware will send an interrupt and then wake up the
device.

WoWLAN is a feature which allows devices to be woken up from suspend
state through WLAN events.
When user enables WoWLAN feature and then let the device enter suspend
state, WoWLAN firmware will be loaded by the driver and periodically
monitors WiFi packets. Power consumption of WiFi chip will be reduced
in this state.
We now implement WoWLAN function in rtw8852ae and rtw8852ce chip.
Currently supported WLAN events include receiving magic packet,
rekey packet and deauth packet, and disconnecting from AP.
