drm/msm/dp: do a force dp_clean while dp disconnect



During connect notification timeout, a disconnect happens 
which also sends a disconnect notification to userspace
before post_enable which completes the semaphore early
and is leading to unclean deinit. USB performs a phy
reset during disconnect. On second connect, dp_host_init
finds core initialized thus creating a noc error while
accessing lclk.
