disp: msm: dp: free DP sim ports during DP sim disable

DP sim ports created during DP sim enable aren't cleared
during disable path. This would retain the last status of
the DP sim port or the connector. This would impact the
next iteration of DP sim test, if done without device
reset. This change will set the port number to 0 during
DP sim disable and clear the memory allocated for these
ports.
