When received frame is decryped by hardware, CCMP PN is checked by
mt76.
When management frame protection (IEEE 802.11w) is used, we must use
a separate counter for tracking received CCMP packet number for the
management frames. The previously used counter was shared with data
frames and that can cause problems in detecting replays incorrectly
for robust management frames.
Add a new counter just for robust management frames to avoid this
issue.

Each firmware piece with mt7915 and mt7921 do not have the MCU header to
reroute the packet to the internal RAM. So we do not need to consider the
MCU header size in __mt76_mcu_send_firmware.
Move the MCU header overhead calculation to mt76_mcu_send_firmware (for
older chipsets)

Signed-off-by: Felix Fietkau <[email protected]>
Add register definitions and read & accumulate them in
the mib polling logic. Note that some registers should not
be read since firmware is already reading them. If driver
reads those, they will be cleared-on-read, and so the firmware
stats will be incorrect.
For these 'do-not-read' stats, add them to the registers definition
so that other developers can be aware of these constraints, but do
not actually read them in the driver.
