[d-kernel] [PATCH] ASoC: AMD: fix conflict use pci-acp driver for ES8336 codec

[nickel на altlinux.org]

From: Vasiliy Kovalev <kovalev at altlinux.org>

For a family of machines whose pci revision ID is 0x1 (renoir),
working with the es8336 codec is only available through the
snd-pci-acp3x driver (raven).

Now we will use a specific driver if there is an acpi device
detected as "ESSX8336" in the machine.

Fixes: 5d33d36f777903 ("ASoC: AMD: add ACP machine driver for ES8336")
