usb: pd: Register typec partner in case AAA is connected

Browse source 
Currently PD driver is not registering typec partner if
analog audio adapter(AAA) is connected to the device. Because of
this, userspace will not be notified of the connected adapter
and there will be no notification seen on UI. This change
registers typec partner in case AAA is connected and unregister
it upon disconnect.
