ALSA: hda: Enhance pm_blacklist option
We want sometimes to keep the runtime PM disabled persistently just
like we did for the PM deny-list in the previous change, e.g. for
testing some buggy device. This patch enhances the existing
pm_blacklist option for achieving it easily.
The default behavior doesn't change -- the driver looks up the deny
list and disables the runtime PM if matches. However, when
pm_blacklist=1 option is set, now the driver disables the runtime PM
completely, just like the deny-list does.
Update the documentation for this option, too.
