Subject: [PATCH v2 2/5] arm64: dts: mt7986: define 3W max power to both SFP on BPI-R3

From: Frank Wunderlich <frank-w@...lic-files.de>

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.

Fixes: 8e01fb15b815 ("arm64: dts: mt7986: add Bananapi R3")
