disp: msm: dp: fix mst port state reporting on hpd unplug

Browse source 
The simulation case uses dp_mst_sim_detect_port which
calls the drm detect port function after checking
the mst state. The non simulation case calls the drm
function directly.

This leads to cases in the disconnect path where
connectors are detected while being unregistered.
This solution merges the simulation and non simulation
cases by using the same detect port function, where a
check for mst state is performed before calling the
drm function.
