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).
