There is a conflict between MediaTek wmt event and msft vendor extension
logic in the core layer since 145373cb1b ("Bluetooth: Add framework for
Microsoft vendor extension") was introduced because we changed the type of
mediatek wmt event to the type of msft vendor event in the driver.
But the purpose we reported mediatek event to the core layer is for the
diagnostic purpose with that we are able to see the full packet trace via
monitoring socket with btmon. Thus, it is harmless we keep the original
type of mediatek vendor event here to avoid breaking the msft extension
function especially they can be supported by Mediatek chipset like MT7921
, MT7922 devices and future devices.

Implement .cmd_timeout to reset the MT7921s device via a dedicated GPIO
pin when the firmware hang or the command has no response.

The driver has to issue the specific command to enable Bluetooth SCO over
the I2S/PCM interface on mt7921s, that is supported since the firmware
with version 20211222191101 was added, and the patch would not cause any
harm even when the old firmware is applied.
The SCO profile with the patch was tested by setting up a VOIP application,
connected to HFP device, checked telephony function can work normally.

Enable wake on bluetooth on mt7921s that can be supported since the
firmware with version 20211129211059 was added, and the patch would
not cause any harm even when the old firmware is applied.
The patch was tested by setting up an HID or HOGP profile to connect a
Bluetooth keyboard and mouse, then putting the system to suspend, then
trying to wake up the system by moving the Bluetooth keyboard or mouse,
and then checking if the system can wake up and be brought back to
the normal state.
