phy: sun4i-usb: support automatically switch PHY0 route to MUSB/HCI
On newer Allwinner SoCs (H3 and after), the PHY0 node is routed to both
MUSB controller for peripheral and host support (the host support is
slightly broken), and a pair of EHCI/OHCI controllers, which provide a
better support for host mode.
Add support for automatically switch the route of PHY0 according to the
status of dr_mode and id det pin.
Only H3 have this function enabled in this patch, as further SoCs will
be tested later and then have it enabled.
As H5 is reusing the PHY driver of H3, this function is also enabled.
