drm/msm/dp: fix runtime_pm handling in dp_wait_hpd_asserted
The function dp_wait_hpd_asserted() uses pm_runtime_get_sync() and
doesn't care about the return value. Potentially this can lead to
unclocked access if for some reason resuming of the DP controller fails.
Change the function to use pm_runtime_resume_and_get() and return an
error if resume fails.
