[PATCH 1/1] ALSA: hda/realtek: Add quirks for ASUS GU604V and GU603V

[Alexandru Sorodoc <ealex95@gmail.com>]

These models use 2 CS35L41 amplifiers using SPI for down-facing
speakers.

alc285_fixup_speaker2_to_dac1 is needed to fix volume control of the
down-facing speakers.

Pin configs are needed to enable headset mic detection.

Note that these models lack the ACPI _DSD properties needed to
initialize the amplifiers. They can be added during boot to get working
sound out of the speakers:
