6.6-stable review patch. If anyone has any objections, please let me know.

------------------

From: Azamat Almazbek uulu <almazbek1608@gmail.com>

[ Upstream commit 32fc4168fa56f6301d858c778a3d712774e9657e ]

The ASUS ExpertBook BM1503CDA (Ryzen 5 7535U, Barcelo-R) has an
internal DMIC connected through the AMD ACP (Audio CoProcessor)
but is missing from the DMI quirk table, so the acp6x machine
driver probe returns -ENODEV and no DMIC capture device is created.

Add the DMI entry so the internal microphone works out of the box.
