arm64: dts: renesas: white-hawk: ethernet: Describe AVB1 and AVB2

Browse Source 
Describe the two Marvell 88Q2110/QFN40 PHYs available on the R-Car V4H
White Hawk RAVB/Ethernet(1000Base-T1) sub-board. The two PHYs are wired
up on the board by default, there is no need to move any resistors which
are needed to access other PHYs available on this sub-board.
