Sankeerth Billakanti fb9ea90d58 disp: msm: dp: reset combo phy if peer_usb_comm is disabled
Some Type-C multi-port adapters which do not support usb connection
are advertising the multi-functionality in DP alt mode. If
multi-functionality is preferred, the DP driver assumes the adapter
supports usb connection and USB phy driver will program the PHY mode
to DP+USB.

In source mode, usb PD driver checks for the peer_usb_connection
of the adapter. If it does not support usb then it will stop usb stack
and update the PHY MODE to USB only mode from phy_suspend path.
The result is, usb may program the combo PHY to usb only mode when DP
is already connected. This is causing AUX read/write timeouts when DP
is trying to access the phy registers.

To fix this issue, a flag in SVID connect handler in usbpd driver to
notify peer_usb_comm support to the DP driver. DP driver will read this
flag and program the phy mode.
