phy: omap-usb2: use *syscon* framework API to power on/off the PHY
Deprecate using phy-omap-control driver to power on/off the PHY, and use *syscon* framework to do the same. This handles powering on/off the PHY for the USB2 PHYs used in various TI SoCs. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
