The usb3 host controller support one usb3 port and one
usb2 port, and these two ports can work independently.

+----------------+ | USB2 |---->| USB2 PHY |
| |---->| PORT | +----------+
| USB3 HOST CTRL | +------+

+------+ +----------+

This patch support usb3 host to disable usb3 port
and only support usb2 port.

In addition, for RK3576, it use pipe_phymode to select
MMU for PCIe/SATA/USB controllers, and the default
pipe_phymode value is 2'b00 which used for PCIe mode.
So it needs to set pipe_phymode for usb even if only
use usb2 port.
