phy: omap-usb2: Adapt phy-omap-usb2 for AM437x
Adapt phy-omap-usb2 driver for AM437x. - Add new comaptible "ti,am437x-usb2" for AM437x - Pass proper data to differentiate AM437x and others. - AM437x doesnot support set_vbus and start_srp. Signed-off-by: George Cherian <george.cherian@ti.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
