rGd4a4960c6559: LinuxKPI: pci: cleanup some code and add support for "pcim" (managed)

Summary

Restructure some code and add support for various "managed" versions
for PCI resource management.
This is beyond of what iwlwifi needs but some was found with other
wireless drivers and it mostly all goes together well.
Add one FreeBSD sepcific feature returning the resource rather than
the handle to allow us to use bus_*() functions in drivers directly.

bz mentioned this in D30686: linuxkpi: Add rom and romlen to struct pci_dev.Jun 7 2021, 9:58 PM

Anyone interested in this or should I go ahead and commit it?

I'd like two days more to look at this.

ACK; That's fine; there's more out and Monday will be okay.

Do you think you'll have a chance in the next 48 hours to look at this or the other remaining reviews?

Two more comments and we are good to go.

sys/compat/linuxkpi/common/src/linux_pci.c
362	Factor this line into the lkpifill_pci_dev() function ?
443	Disable busmaster too?

Fold dev.release into lkpifill_pci_dev().

sys/compat/linuxkpi/common/src/linux_pci.c
362	Done. I just need to find the other change adding the 2nd case of this assignment and sort it there as well then.
443	pcim_enable_device() doesn't track that; and not under "enable_io". This is merely the private opposite of pci_enable_device().
