Realtek DHC (digital home center) RTD SoCs support DWC3 XHCI USB
controller. Added the driver to drive the USB 3.0 PHY transceivers.
Note: New driver, remove the port status notification on legacy USB PHY.
Use the generic PHY to notify the usb device connect and disconnect.
To avoid using these PHYs would require describing the very same
PHY using both the generic "phy" property and the deprecated "usb-phy"
property.

This reverts commit 134e6d25f6.
The recently added Realtek PHY drivers depend on the new port status
notification mechanism which was built on the deprecated USB PHY
implementation and devicetree binding.
Specifically, using these PHYs would require describing the very same
PHY using both the generic "phy" property and the deprecated "usb-phy"
property which is clearly wrong.
We should not be building new functionality on top of the legacy USB PHY
implementation even if it is currently stuck in some kind of
transitional limbo.
Revert the new Realtek PHY drivers for now so that the port status
notification interface can be reverted and replaced.
