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.
