ASoC: SOF: Intel: refactor i915_get/put functions
The current interface to control i915 display power is misleading.
The hda_codec_i915_get() and hda_codec_i915_put() names suggest
a refcounting based interface. This is confusing as no refcounting
is done and the underlying HDAC library interface does not support
refcounts eithers.
Clarify the code by replacing the functions with a single
hda_codec_i915_display_power() that is aligned with
snd_hdac_display_power().
