From: Mark Pearson <markpearson at lenovo.com>

[ Upstream commit 19a0aa9b04c5ab9a063b6ceaf7211ee7d9a9d24d ]

More laptops identified where the AMD ACP bridge needs to be blocked
or the microphone will not work when connected to HDMI.

Use DMI to block the microphone PCM device for these platforms.
