arm64: dts: rockchip: Add gmac1 and change network settings of bpi-r2-pro

New Version (v1.0) of R2 pro has swapped gmacs compared to the v00.

WAN-Port is now on gmac1 (RTL8211F) and lan-ports on gmac0 with mt7531
switch.

There is already a mt7531 dsa driver in mainline, but it needs to be
modified to work for this board.

Pre-1.0 version was not sold, so the setting can be savely overridden.
