In Realtek SoC, the parameter of usb phy is designed to can dynamic
tuning base on port status. Therefore, add a notify callback of phy
driver when usb connection/disconnection change.

2.34.1
Recently added Realtek PHY driver depends on new port status
Notification mechanism built on the deprecated USB PHY implementation.
It's broken by design.
Therefore, USB port status notifications on legacy USB PHYs should be
removed. New mechanism for connect and disconnect USB devices using
to replace it on generic phy.
Additionally, the generic phy only specifies primary_hcd in the original
design. Added specific "usb2-phy" on primary_hcd and "usb3-phy" on
shared_hcd.
In Realtek SoC, the parameter of usb phy is designed to can dynamic
tuning base on device connect and disconnect. Therefore, add a notify
callback of generic phy driver when usb device connection change.
Check if portstatus is USB_PORT_STAT_CONNECTION and portchange is
USB_PORT_STAT_C_CONNECTION.
1. The device is connected, notify phy driver to calibrates
the phy parameters.
2. The device disconnects, also notify driver to calibrates
the phy parameters.

2.34.1
Same as phy-rtk-usb2.c
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.
