- If a PCI device is not present, then a 32-bit read_config() is going to
return 0xffffffff not 0xffff.
- For the 82454NX chipset, the MIOC that we read the bus numbers of the
various host-PCI bridges from is at function (slot) 0x10 not 0x0.

1. Detect the revision of the Rhine chip we're using.
2. Use the force reset command on revisions which support
it whenever the normal reset command fails.
This should solve a wide range of "my vr0 locks up with reset
failed messages" problems. (Although the root causes should
be eventually tracked down.)

to PCI bridge can be read be evaluating the _BBN method of the host to PCI
device. Unfortunately, there appear to be some lazy/ignorant/moronic/
whatever BIOS writers that return 0 for _BBN for all host to PCI bridges in
the system. On a system with a single host to PCI bridge this is not a
problem as the child bus of that single bridge will be bus 0 anyway.
However, on systems with multiple host to PCI bridges and l/i/m/w BIOS
writers this is a major problem resulting in all but the first host to
PCI bridge failing to attach. So, this adds a workaround.
If the _BBN of a host to PCI bridge is zero and pcib0 already exists
and is not us, the we use _ADR to look up our PCI function and slot
(we currently assume we are on bus 0) and use that to call
host_pcib_get_busno() to try and extract our bus number from config
registers on the host to PCI bridge device. If that fails, then we make
an evil assumption that ACPI's _SB_ namespace lays out the host to PCI
bridges in ascending order and use our pcib unit number as our bus
number.

- Fiddle the right bits in the cn input and output routines to disable port
interrupts and enable visibility of the masked interrupt status bits.
- Register a shutdown final event handler to put the chip back in the mode
that the prom expects.

o Use 32-bit unsigned types for things that really are 32-bit quantities,
not bus_addr_t. These are not the same as a bus_addr_t, so don't use
that here. Harmless on i386, introduced problems on sparc64.

that none of them are.
