[PATCH] x86, mrst: Add audio driver bindings

[Alan Cox <alan@lxorguk.ukuu.org.uk>]

From: Vinod Koul <vinod.koul@intel.com>

This patch adds the sound card bindings for Moorestown (pmic_audio) and
the Medfield platform (msic_audio) as IPC devices. This ensures they will be
created at the right time.
