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 <nbd@nbd.name>

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.
