[PATCH] ALSA: docs: remove references to removed CONFIG_SND_HDA_POWER_SAVE

[Ethan Nelson-Moore]

The CONFIG_SND_HDA_POWER_SAVE option was removed in commit 83012a7ccbb9
("ALSA: hda - Clean up CONFIG_SND_HDA_POWER_SAVE"), but references to
it remained in documentation. Remove them.

Discovered while searching for CONFIG_* symbols referenced in code but
not defined in any Kconfig file.
