mediatek: add Ubiquiti UniFi 6 LR v2 targets

Add targets:
 * Ubiquiti UniFi 6 LR v2
 * Ubiquiti UniFi 6 LR v2 (U-Boot mod)

This target does not have a RGB led bar like v1 did

Used target/linux/ramips/dts/mt7621_ubnt_unifi.dtsi as inspiration

The white dome LED is default-on, blue will turn on when the system is
in running state
