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 commit drops the board specific defconfig in favor of proper BSP
support for the FriendlyARM NanoPi R2S to Infix as part of the default
Aarch64 build.
The name FriendlyARM was elected over FriendlyELEC ("new" name) to be
consistent with both kernel and Buildroot naming standards.

This commit consolidates all BSP support files into the Buildroot standard
board/ directory. The concept of selectable boards in menuconfig remains
as-is but now lives in board/ instead.
Drop support for board-specific post-build.sh scripts, not needed atm. and
we should really use Buildroot _POST_INSTALL_HOOKS in the board .mk files
instead.
