Fix BPi-R64 onboard WiFi probing

Browse Source 
The mt7622 soc has a built-in wmac, same driver as the mt7615, but
it lacked MODULE_DEVICE_TABLE() so udev could not autoload driver
and firmware.

This commit also adds the wmac+bluetooth specific firmware.

## Platform Notes
### WiFi
The MT7622 SoC includes a built-in WMAC that provides 2.4 GHz 802.11b/g/n/ac
(2×2) — there is no 5 GHz capability from the onboard radio.
For dual-band operation, a PCIe card can be fitted in one of the two Mini PCIe
slots. The [Banana Pi BPI-MT7615][bpi-mt7615] is a purpose-built dual-band
(2.4 + 5 GHz, 802.11ac 4×4) module designed for BPI router boards and is a
natural fit. With it installed, Infix will use it in preference to the onboard
WMAC for the `wifi0-ap` interface.

Subject: [PATCH] wifi: mt76: mt7615: add MODULE_DEVICE_TABLE for mt7622 wmac
Organization: Wires
Without MODULE_DEVICE_TABLE(of, ...) the OF compatible alias is never
exported to modules.alias, so udev cannot autoload mt7615e when the
mediatek,mt7622-wmac platform device is probed. Add the export so the
module loads automatically on BPI-R64 and similar MT7622-based boards.
