Takashi Iwai 36a38c53b4 ALSA: hda: Fix discovery of i915 graphics PCI device 
It's been reported that the recent fix for skipping the
component-binding with D-GPU caused a regression on some systems; it
resulted in the completely missing component binding with i915 GPU.

The problem was the use of pci_get_class() function.  It matches with
the full PCI class bits, while we want to match only partially the PCI
base class bits.  So, when a system has an i915 graphics device with
the PCI class 0380, it won't hit because we're looking for only the
PCI class 0300.

This patch fixes i915_gfx_present() to look up each PCI device and
match with PCI base class explicitly instead of pci_get_class().

Fixes: c9db8a30d9 ("ALSA: hda/i915 - skip acomp init if no matching display")
