mediatek: re-enable mt7622-rfb1-ubi with changed partition layout

The boot loader does not have a fixed size limit for the kernel,
so we're free to change the layout. This may break sysupgrade, but a fresh
flash from initramfs works.

Fixes: 6e2962d4c548 ("mediatek: mt7622: skip build for MT7622 rfb1 (UBI)")
