Adding CPSW phy-id, CPSW and MDIO pinmux configuration for active and
sleep states and enable them in board evm dts file.
Signed-off-by: Mugunthan V N mugunthan...@ti.com

Adding device tree entry for CPSW to make it work in Switch mode.
Patches are tested on top of Nishanth's PM tree for v3.17 [1] and pushed
my tree to [2].
Did a boot test with CPSW and ping test with suspend/resume, the boot logs
on DRA72x EVM are posted at [3]
This patch depends on the DRA7xx CPSW support patch series [4] and one driver
patch (47276fc drivers: net:cpsw: fix probe_dt when only slave 1 is pinned out)
which is already present in linux-next
