Instead of building all U-Boot variants by default, build only those
needed by the selected board(s).

MediaTek published their current U-Boot patchset on github:
https://github.com/mtk-openwrt/u-boot/commits/mtksoc
Import the platform patches from there (`00-mtk-*.patch`), arrange,
them nicely, drop no longer needed local patches and rebase on top of
U-Boot 2021.04-rc3.
Tested and works well on Linksys E8450 (snand-1ddr) as well as
Bananapi BPi-R64 (sdmmc-2ddr, emmc-2ddr).

Provide U-Boot variants for SD-card as well as eMMC boot, so we can
generate whole-disk images for the device.
While at it, rename 'mt7622' to 'mt7622-rfb1' to make it less confusing
now that more boards are being added.
Thanks to Frank Wunderlich (@frank-w) for making that nice SVG image
explaining the MMC boot process[1] and for providing the necessary
binary header blobs.

Build U-Boot for the Linksys E8450 in order to have support for UBI.
The loader has a default environment with scripts handling the reset
button as well as fall-back to recovery firmware. If the loader comes
up without a valid environment found in UBI, it will automatically
make sure UBI is formatted and create a new environment and proceed
to load recovery firmware (either from UBI or via TFTP if recovery is
corrupted or unavailable).
If the button is held down during power-on, the yellow status LED
turns on and the bootloader environment is reset to factory defaults.
If the button is released at this point, the recovery firmware (if
existing) is loaded from UBI and booted.
If the button is continously held down even beyond the point that
the yellow LED turned on, the loader will try to load the recovery
firmware via TFTP from server 192.168.1.254, write it to UBI and
boot.

Ever since this package was introduced, the SDK for mt7629 failed to
build as it started failing on this package.
Fixed by porting Hauke's similar patch for uboot-sunxi to uboot-mediatek.

For building full SD/eMMC images for Banana Pi R2 we'll want a u-boot
image built for that platform.
