Patches to add support for Rockchip usb phys.Add a new Rockchip
usb phy driver and modify dwc2 controller driver to make dwc2
platform devices support a generic PHY framework driver. This
patch set has been tested on my rk3288-evb and power off the usb
phys would reduce about 60mW power budget in total during sustem
Changes in v7:
- Update bindings doc
- Accept Kishon's comments to use phandle args to find a phy
struct directly and get rid of using a custom of_xlate
- Update dtsi for new usb phy driver.
Changes in v6:

Changes in v5:
- Adjust entry order of example devicetree node in document.
- reorder the phy dt node to a correct position.
Changes in v4:
- Updata description for phy device tree subnode.
- Get number of PHYs from device tree.
- Model each PHY as subnode of the phy provider node.
- Add phy subnodes.
Changes in v3:
- Use BIT macro instead of bit shift ops.
- Rename the config entry to PHY_ROCKCHIP_USB.
- Fix coding style: both branches of the if() which only one
branch of the conditional statement is a single statement
should have braces.
- No need to test dwc2->phy for NULL before calling generic phy
