After option PCI_RESOURCE was enabled by default, the new kernel didn't detect
my hard disk driver controller.

Boot a PCI_RESOURCE kernel on my hardware.
Some debugging that was requested in a current-users thread:
ACPI dump (without PCI_RESOURCE):
https://netbsd.org/~wiz/no_pci_resource.asl.gz
dmesgs:
https://netbsd.org/~wiz/dmesg.vx.NO_PCI_RESOURCE
https://netbsd.org/~wiz/dmesg.vx.PCI_RESOURCE
`pcictl pci0 dump -b <bus> -f <func> -d <dev>`:
https://netbsd.org/~wiz/pcictl.NO_PCI_RESOURCE
https://netbsd.org/~wiz/pcictl.PCI_RESOURCE
>Fix:
Revert the option change, or fix this.

building a kernel with "options no PCI_RESOURCE" allows hdaudio to attach a=
s expected.

no-pci-resource.dmesg
no-pci-resource.pcictl-dump
Also saw an ACPI related panic when shutting down a GENERIC kernel between =
tests (may or may not be related). recursive panic, so no crashdump but scr=
een shot "acpi-panic.webp" in same directory as above
