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.
