Minor CIS resource allocation code cleanup
Remove some fairly useless debug writes.
This finishes the work to move as much cardbus code as possible into
pci. We wind up removing 800-odd lines from cardbus.c: we go from
1285 to 400 lines.

- Make it so reusing mbufs when we can't allocate (or map) new ones
actually works. We were previously trying to reuse a mbuf which
was already bus_dmamap_unload()'ed.

- Ignore BUS reset events while BUS reset phase. We can't clear that flag

UltraSPARCs, and an eeprom attachment for fhc, which allows the date
to be set properly on these machines. Central is a wierd bus which
seems to only ever have 1 fhc attached to it. FHC (FireHose Controller)
is another wierd bus with various things on it depending where its attached.
The fhc attached to central has eeprom and zs, and the fhcs which attach
directly to nexus have simm-status, environment and other nodes, none of
which I'll probably ever have documentation for.
Thanks to Ade Lovett for providing access to an 8 cpu e4500.
#if'ed out for a while. Complete the deed and tidy up some other bits.
We need to be able to call this stuff from outer edges of interrupt
handlers for devices that have the ISR bits in pci config space. Making
the bios code mpsafe was just too hairy. We had also stubbed it out some
time ago due to there simply being too much brokenness in too many systems.
This adds a leaf lock so that it is safe to use pci_read_config() and
pci_write_config() from interrupt handlers. We still will use pcibios
to do interrupt routing if there is no acpi.. [yes, I tested this]

is encoded in the PCI BAR. The latter is more reliable.
This allows the sio/modem function of the Xircom RealPort ethernet+modem
card to work. Note that there still seem to be issues with sio_pci not
releasing resources on detach.
pci busses implement this.
Also minor comment smithing in cardbus. Fix copyright to this year
with my name on it since I've been doing a lot to this file.

on the fly and read into userland one at a time, this costs very
little total memory. The pnpinfo sizes of pccard is more than 64
bytes due to the length of the strings that man cards have in their
CIS.
- Don't initiate bus reset even if probe failed for some nodes to prevent
infinite bus reset loop.

Note: we do not have socheckuid() in RELENG_4, ip_fw2.c uses its

uid rules correctly. I will MFC the diff for code consistency.
