[PATCH] ASoC: SOF: Intel: hda: Initialize HDA controller after i915 init

[Ranjani Sridharan <ranjani.sridharan@linux.intel.com>]

On some platforms, sound card registration fails when a HDMI
monitor is not connected. This is caused by a recent commit
that switched the order in which the HDA controller and the
i915 are initialized. Initializing the i915 before initializing
the HDA controller fixes the problem.

Fixes: be1b577d01787c ("ASoC: SOF: Intel: hda: fix the hda init chip")
