[alsa-devel] [PATCH 1/2] ASoC: Intel: bytcr_rt5640: Add quirk for the Prowise PT301 tablet

Add a quirk for the Prowise PT301 tablet, this BYTCR tablet has no CHAN
package in its ACPI tables and uses SSP0-AIF1 rather then SSP0-AIF2 which
is the default for BYTCR devices.

Also it uses IN1 for its MIC and JD2 for jack-detect, rather then the
default IN3 and JD1.
