ALSA: hda/tas2781: do not call pm_runtime_force_* in system_resume/suspend
[ Upstream commit 5f51de7e30c7282162a631af8a425b54a4576346 ]
The runtime_resume function calls prmg_load and apply_calibration
functions, but system_resume also calls them, so calling
pm_runtime_force_resume before reset is unnecessary.
For consistency, do not call the pm_runtime_force_suspend in
system_suspend, as runtime_suspend does the same.
