Sound: [Under Development] Alder Lake-H

[ziaee]

Summary

I have added these two lines following your examples in recent commits, they build and correct dmesg output,
but still getting no devices installed from # cat /dev/sndstat as well as mixer: (null): no such mixer from # mixer

Here are some seemingly relevant outputs:

# dmesg | grep hda
hdac0: <Intel Alder Lake-H HDA Controller> mem 0x618e1d0000-0x618e1d3fff,0x618e
000000-0x618e0fffff at device 31.3 on pci0

# pciconf -lv
hdac0@pci0:0:31:3:      class=0x040100 rev=0x01 hdr=0x00 vendor=0x8086 device=0
x51c8 subvendor=0x1028 subdevice=0x0b29
    vendor     = 'Intel Corporation'
    device     = 'Alder Lake PCH-P High Definition Audio Controller'
    class      = multimedia
    subclass   = audio

# sysctl dev.hdac.0.pindump=1
dev.hdac.0.pindump: 0 -> 0

Test Plan

This builds, and corrects dmesg output, but doesn't enable sound support yet.

Oops, please forgive the noise, I see now that alder lake-p is the die and it's ID is already in the table a little lower.
