Ze Huang fe4bc1a086 phy: spacemit: support K1 USB2.0 PHY controller ...

The SpacemiT K1 SoC includes three USB ports:

- One USB2.0 OTG port
- One USB2.0 host-only port
- One USB3.0 port with an integrated USB2.0 DRD interface

Each of these ports is connected to a USB2.0 PHY responsible for USB2
transmission.

This commit adds support for the SpacemiT K1 USB2.0 PHY, which is
compliant with the USB 2.0 specification and supports both 8-bit 60MHz
and 16-bit 30MHz parallel interfaces.
