arm64: dts: exynos: Enable USB in Exynos850 



Add USB controller and USB PHY controller nodes for Exynos850 SoC.

The USB controller has next features:
  - Dual Role Device (DRD) controller
  - DWC3 compatible
  - Supports USB 2.0 host and USB 2.0 device interfaces
  - Supports  full-speed (12 Mbps) and high-speed (480 Mbps) modes with
    USB device 2.0 interface
  - Supports on-chip USB PHY transceiver
  - Supports up to 16 bi-directional endpoints (that includes control
    endpoint 0)
  - Complies with xHCI 1.00 specification

Only USB 2.0 is supported in Exynos850, so only UTMI+ PHY interface is
specified in "phys" property (index 0) and PIPE3 is omitted (index 1).
