disp: msm: dp: inform multi-func support to usb driver

The usb controller driver does not know if DP is
supported / connected and whether it is operating in
concurrent mode. So, whenever there is a ucsi role switch
call to the usb controller driver, it will reset the usb
phy irrespective of DP connection.

The phy reset while DP driver is still processing cable
connect or disconnect will cause aux timeout or NOC errors.
This change will inform the usb controller driver about the
multi_func mode support to convey how many lanes DP will
be using.
