Add a quirk for the HP Pro Tablet 408, 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.

It also uses DMIC1 for the internal mic rather then the default IN3
and it uses JD2 rather then the default JD1 for jack-detect.
