Add a quirk for the Prowise PT301 tablet, this BYTCR tablet has no CHAN

Also it uses IN1 for its MIC and JD2 for jack-detect, rather then the
default IN3 and JD1.
Looks like someone was trying hard to avoid using defaults...Oh well.
FWIW:
Well in practice more BYTCR devices seem to use SSP0-AIF1 rather then
SSP0-AIF2, but I don't want to change the driver defaults at this point
and most BYTCR devices do have a CHAN package in their ACPI tables.
As for using IN1+JD2 rather then IN3+JD1 (which seem to be the most
if not only used combos) in my experience there is pretty much a 50/50
split in which devices uses which combo.
I've a table with the correct settings for most of the device which I have
here: https://github.com/jwrdegoede/sunxi-fedora-scripts/blob/master/x86-codec-info
Both patch 1 and 2
