[PATCH] arm64: dts: mediatek: mt7988a-bpi-r4: allow hw variants of bpi-r4

From: Frank Wunderlich
Date: Fri Feb 07 2025 - 09:10:51 EST

From: Frank Wunderlich <frank-w@xxxxxxxxxxxxxxx>

Sinovoip has released other variants of Bananapi-R4 board.
The known changes affecting only the LAN SFP+ slot which is replaced
by a 2.5G phy with optional PoE.

As the SFP-Ports are not upstreamed yet this patch simply renames the
current board dts to dtsi, creating new dts for the board including
the new dtsi and move i2c-mux channel for sfp lan to board dts.
