ARM: dts: Add support for DRA72x family of devices DRA722 is part of DRA72x family which are single core cortex A15 devices with most infrastructure IPs otherwise same as whats on the DRA74x family. So move the cpu nodes into dra74x.dtsi and dra72x.dtsi respectively. Also add a minimal dra72-evm dts file.

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.

So, use the fact that control module of DRA7 is setup such that no matter what mode one configures it, GPIO option is always hardwired in - use GPIO mode for SDcard detection. [peter.ujfalusi@ti.com] The power line feeding the SD card is also used by other devices on the EVM.

ARM: dts: dra72-evm: remove cpsw gpio hogging and add mode-gpios With the current implementation of GPIO hogging and with gpio-pcf857x is built as module, ethernet doesn't work on boot and doesn't throw any error/warning to user. Ethernet becomes operational when inserting gpio-pcf857x module, even this time there is no error/warning logs to user that ethernet is operational. When using with NFS rootfs and gpio-pcf857x as module, board doesn't boot as it doesn't get any ip address and doesn't throw any error/warning. To over come this, now cpsw driver tries to get mode-gpios. When gpio-pcf857x is built as module it will throw error, so that user can decide either to built in gpio-pcf857x to continue with nfs boot or choose alternate rootfs filesystem like sd/ramdisk. When using mmc/ramdisk as root fs, cpsw will probe defer and re-probes again when gpio-pcf857x module is inserted and ethernet becomes operational.
