Nishanth Menon a4240d3af6 ARM: dts: Add support for dra72-evm rev C (SR2.0)
DRA72-EVM now has an upgrade to Rev C with SR2.0 silicon. As part of
this change, a few updates were factored in that were software
incompatible with previous board in few areas:
- We now use DP83867 ethernet phy instead of older DP838865 which fails
  in certain use cases.
- Two Ethernet ports now instead of the single one in rev B.
- polarities changed for certain pcf gpios
- Due to SoC phy current requirements, VDDA supplies are split between
 ldo3 and ldo2 (ldo2 was previously unused). NOTE: DSS (VDDA_VIDEO) is
 still supplied by ldo5, HDMI is now supplied by LDO2 instead of using
 LDO3.

NOTE: It does not make much sense to spin off a new board compatible
flag since there is no real benefit for the same.
