We used to have a variable declaration with __free() initialized with
NULL. This was to keep the old coding style rule, but recently it's
relaxed and rather recommends to follow the new rule to declare in
place of use for __free() -- which avoids potential deadlocks or UAFs
with nested cleanups.
Although the current code has no bug, per se, let's follow the new
standard and move the declaration to the place of assignment (or
directly assign the allocated result) instead of NULL initializations.

The release of temporary kmalloced buffers can be nicely handled via
the standard __free(kfree).
Only code refactoring, and no behavior change.

The new macro CLASS(snd_hda_power_pm) can replace the manual
snd_hda_power_up_pm() and _down() calls gracefully.
A part of the code in codec_exec_verb() is factored out to a function,
so that the auto-cleanup can be well scoped.
Merely cleanups and no functional changes.

The snd-hda-codec module contains the most of common code used by both
HD-audio controller and codec drivers, and it's basically independent
from PCI. Let's move the code to sound/hda/common directory as a part
of code reorganization.
The hda_ prefix is dropped from the most of file names as it's rather
superfluous.
