Log Message:
virtio_pci_bus_space_write_8: don't use bus_space_write_8.
The standard says:
4.1.3.1 Driver Requirements: PCI Device Layout
For device configuration access, the driver MUST use ... 32-bit
wide and aligned accesses for ... 64-bit wide fields. For 64-bit
fields, the driver MAY access each of the high and low 32-bit parts
of the field independently.
NB: "MAY" in this text refers to "independently" (i.e. the order of
accesses) not "32-bit" (which is restricted by the earlier "MUST").
Note also that virtio_{read,write}_device_config_8 in virtio.c already
uses two 32-bit accesses.
