Subject: arm64: dts: mt7986: define 3W max power to both SFP on BPI-R3
From: Frank Wunderlich <frank-w@xxxxxxxxxxxxxxx>
commit 6413cbc17f89b3a160f3a6f3fad1232b1678fe40 upstream.
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.
