ALSA: hda - Clarify CONFIG_SND_HDA_RECONFIG usages
Since the recent rewrite of HD-audio infrastructure, CONFIG_SND_HDA_RECONFIG has a slightly different meaning. In the earlier versions, it implicitly assumed only the usage via hwdep sysfs entries. Meanwhile, in the recent version, this option is meant to enable the reconfig code in HD-audio driver, which may be used by the patch loader without hwdep interface. This patch tries to clarify the usage pattern a bit better, hopefully avoid the further confusion.
