Daniel Golle 06a150aed7 mediatek: re-add dropped properties on BPi-R3
Unfortunately some device tree properties have slipped under the table
when switching from our downstream device tree.

Bring back 3W power for SFP cages and restore thermal trip points to
make sense again.

Subject: [PATCH 20/22] arm64: dts: mt7986: define 3W max power to both SFP on
BPI-R3
All SFP power supplies are connected to the system VDD33 which is 3v3/8A.
Set 3A per SFP slot to allow SFPs work which need more power than the
default 1W.
