Daniel Golle a387c62114 mediatek: dts: rename mt7981.dtsi to mt7981b.dtsi
Upstream uses a different filename, so lets rename our downstream
mt7981.dtsi to mt7981b.dtsi and update the device tree of all
MT7981 boards accordingly.
This is to prepare for the switch to Linux 6.12 which is going to
use the upstream mt7981b.dtsi (plus some patches on top).
