Add support of usb host and gadget function for rk3328.
Changed in v8:
- Convert CONFIG_USB_DWC2 to a Kconfig entry
Changed in v7:
- Romove unused variable ‘prop’ in dwc2 driver
Changed in v6:
- Rebase on the newest code of master branch
- Make xhci-rockchip driver depend on DM_REGULATOR and DM_USB
- Remove #ifdef DM_RERULATOR and DM_USB in xhci-rockchip driver
- Use dev_read_boot() instead of fdt_getprop() in dwc2 driver
Changes in v5:
- Propagate return value and print error message when failed
Changes in v4:
- Splite patch [U-boot,v3,04/10] into two patches
- Define set vbus as empty function if the macros aren't set
- Prepare a mask and set capabilities in GUSBCFG register once
Changes in v3:
- Revert change of macro definition in dwc2 driver
- Support host mode without HNP/SRP capability through DTS
Changes in v2:
- Add commit messages
- Split patch [U-boot,7/8] into two patches
- Use fixed regulator to control vbus instead of gpio

The xhci-rockchip driver depends on DM_REGULATOR and DM_USB.
So add dependent features for xhci-rockchip driver in Kconfig.

Use fixed regulator to control the voltage of vbus. Enable vbus
supply when usb start and disable vbus supply when usb stop.

fixed regulator node in DTS for xhci driver.
