[PATCH] ALSA: hda: Match only Intel devices with CONTROLLER_IN_GPU()

[Bjorn Helgaas]

From: Bjorn Helgaas <bhelgaas@google.com>

CONTROLLER_IN_GPU() is clearly intended to match only Intel devices, but
previously it checked only the PCI Device ID, not the Vendor ID, so it
could match devices from other vendors that happened to use the same Device
ID.

Update CONTROLLER_IN_GPU() so it matches only Intel devices.

Fixes: 535115b5ff51 ("ALSA: hda - Abort the probe without i915 binding for HSW/B")
