skylake: Add Audio DSP device
Add the Audio DSP device for skylake as a PCI driver with a static
scan_bus handler so generic devices can be declared under it.
This is for devices like the Maxim 98357A which is connected on the
I2S bus for data but has no control channel bus and instead just has
a GPIO for channel selection and power down control and needs to
describe that GPIO connection to the OS via ACPI.
