Almost rewrite xbridge PCI resource allocation:

- introduce an interface for widget drivers to ask the xbow to map arbitrary
  views of their address space, in addition to the low 16MB. This operation
  may fail or map a subset range of what the caller asked for, depending on
  the platform we're running on.
- use this in xbridge to set up views on the direct memory and i/o spaces,
  to map devices resources when they don't fit in one of the devio small
  ranges (limited to 2MB anyway). These views are only allocated when
  devio can't do the job, so as not to consume too many resources on
  Origin family systems where such views are scarce resources (and
  shared accross the whole crossbow).

This makes pci devices with large resource needs configure correctly.

While there, fix programming of 64 bit memory BAR; this makes bge(4)
work.

Tested on Octane (with Bridge revision < 4 and >= 4), Origin 200 (Bridge >= 4)
and Fuel (XBridge).
