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.

Add board support for the BananaPi BPI-R4 router board, based on the
MediaTek MT7988A (Filogic 880) SoC with quad-core Cortex-A73 CPU.
The BPI-R4 is the successor to the BPI-R3 but uses entirely different
silicon: the internal switch runs at 2.5 GbE per port, the two SFP+
uplinks use native USXGMII at up to 10 Gbps, and WiFi is provided by
a MediaTek MT7996E PCIe module supporting tri-band WiFi 7 (2.4/5/6 GHz).
Two board variants, BPI-R4-2g5 and BPI-R4P, replace one SFP+ cage with
a 2.5 GbE RJ45 port (using the MT7988A internal 2.5G PHY); the R4P adds
an optional PoE daughterboard on that port. Both use the upstream
mt7988a-bananapi-bpi-r4-2g5 device tree.
Interfaces:
- Standard R4: eth1 (gmac1/sfp2 LAN cage) → sfp2, eth2 (gmac2/sfp1 WAN cage) → sfp1
- R4-2g5/R4P: eth1 (2.5G PHY) → wan, eth2 (gmac2/sfp1 WAN cage) → sfp1
Factory reset / WPS button (GPIO14, active-low): detected by U-Boot at
boot for factory reset; reused by Linux as KEY_WPS_BUTTON at runtime.
eMMC install note: the MT7988A eMMC (pins 38-49) and SD card (pins 32-37)
use separate physical pads so there is no electrical bus sharing, unlike
some BPi-R3 configurations. However, a single MMC controller
(mmc@11230000) handles both, so only one is active per boot session.
The eMMC install procedure therefore still requires an intermediate SPI
NAND bootloader step until a Linux-side install path is tested.
SD card build (bpi_r4_sd_boot_defconfig) now uses the new
mt7988a_bpir4_sd U-Boot defconfig with cap-sd-highspeed enabled,
giving 50 MHz SD transfers instead of the previous 25 MHz legacy mode.
Also adds MT7988/MT7996 firmware support to the buildroot linux-firmware
package, for 2.5 GbE port PHY and WiFi7 extension board, and updates the
aarch64_defconfig, aarch64_minimal_defconfig, the arch README, CI
boot/image workflows, mkimage.sh, and the ChangeLog.

This fix the instability of the display on soft reboots,
previous it required a powercycle to get display to work properly
Add patches from rpi-linux, and a small fixup from me.
