rockchip: dts: rk3328: Sync device tree files from Linux

This syncs rk3328 device tree files from the Linux kernel next-20200324.
The last commit to touch these files is:

    b2411befed60 ("arm64: dts: add bus to rockchip amba nodenames")

Additional changes not yet in the Linux kernel include:

    arm64: dts: rockchip: rk3328: drop #address-cells, #size-cells from grf node
    arm64: dts: rockchip: rk3328: drop non-existent gmac2phy pinmux options
    arm64: dts: rockchip: rk3328: Replace RK805 PMIC node name with "pmic"

Changes include:

  - conversion of raw pin numbers to macros
  - removal of deprecated RK_FUNC_* macros
  - update of device tree binding headers
  - new devices
  - device tree cleanups
  - gmac2phy disabled in -u-boot.dtsi as it is not supported in U-boot

This includes a re-ordering of the USB device nodes compared to upstream
Linux, moving the dwc2 OTG controller after the EHCI/OHCI nodes. This is
currently required as otherwise the dwc2 controller would not be able to
detect devices in some cases. This may be due to lack of USB PHY support
in U-boot.
