Add a comment explaining that we expect the memory controller
...
registers to already be subregion'd off, and actually init
the PCI DMA tag.

Add support for PCI DMA on the i80312. We currently just do
...
DMA via the Secondary Inbound window, for now. Will probably
need to revisit this at some point.
Require that the board-specific i80312 front-end slice off a
subregion for the memory controller before calling i80312_attach(),
and fix a bug in the IQ80310 front-end that caused the Secondary
Inbound window to be configured incorrectly.

Add support for configuring the PCI bus (starting with the Secondary
...
bus only, for now).
XXX Some cleanup wrt. pci_conf_interrupt() needs to happen.

Clear the Master Abort after reading config space for a non-existent
...
PCI device. Disable debugging messages, as PCI config space works now.

Disable the ATU interrupt sources (i.e. interrupts that occur when
...
we get Master or Target aborts).

Snapshot of work-in-progress for Intel i80312 Companion I/O chip;
...
just basic Inbound and Outbound window setup is done, PCI configuration
space access (not quite working yet), and I/O and Memory space routines
so far.

Adjust the way the PMMRs are defined -- offsets from a base, not
...
absolutes. Also, add PPB and more ATU registers.
