Stanley Chang a08799cf17 usb: phy: add usb phy notify port status API 
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 port status change.

The Realtek phy driver is designed to dynamically adjust disconnection
level and calibrate phy parameters. When the device connected bit changes
and when the disconnected bit changes, do port status change notification:

Check if portstatus is USB_PORT_STAT_CONNECTION and portchange is
USB_PORT_STAT_C_CONNECTION.
1. The device is connected, the driver lowers the disconnection level and
   calibrates the phy parameters.
2. The device disconnects, the driver increases the disconnect level and
   calibrates the phy parameters.

When controller to notify connect that device is already ready. If we
adjust the disconnection level in notify_connect, the disconnect may have
been triggered at this stage. So we need to change that as early as
possible. The status change of connection is before port reset.
Therefore, we add an api to notify phy the port status changes. In this
stage, the device is not port enable, and it will not trigger
disconnection.
