NetBSD/src 83CID6x — sys/dev/pci nvme_pci.c xhci_pci.c, sys/dev/pci/ixgbe ixgbe.c ixv.c
Nowadays some UEFI BIOSes don't enable some PCI devices' address decoding.
To resolve this problem, pci_map.c rev. 1.34-1.36 changed the
pci_mapreg_(sub)map()'s to set the decode bit if it's not set. It's good for
almost all drivers, but some other drivers don't use pci_mapreg_map().
In drivers which don't use pci_mapreg_map(), some of them expilicitly enable
decoding but others don't. Add code to enable decoding to them.
