ALSA: hda - Move in_pm accessors to HDA core
The in_pm atomic in hdac_device is an important field used as a flag
as well as a refcount for PM. The existing snd_hdac_power_up/down
helpers already refer to it in the HD-audio core code, while the code
to actually setting the value (atomic_inc() / _dec()) is open-coded in
HDA legacy side, which is hard to find.
This patch adds the helper functions to set/reset the in_pm counter to
HDA core and use them in HDA legacy side, for making it clearer who /
where the PM is managed.
There is no functional changes, just code refactoring.
