(1) added prom property retrieval on sparc
(2) added multiple domain support on sparc
(3) use kernel device as mapping device
(4) performance improvements by removing redundant ioctl

Solaris support for multiple PCI segments (domains)

1. Removed hardcoded maximum size of 256 PCI devices, which is
too small for large systems. The number of devices is dynamically
resized as needed.

2. pci_device_solx_devfs_probe() no longer walks the device tree
from the very top ("/") but instead starts at the nexus which
owns the bus. Performance optimization for systems with multiple
bus nodes (including systems with just one segment/domain).

3. Added support for multiple domains/segments. Code tested
on kernels with and without multiple segment support so it should
be safe to integrate independent of the kernel version.

Sun bug 6811468: pci_device_solx_devfs_probe accesses freed memory

di_fini() is being called in pci_device_solx_devfs_probe()
The di_fini (3DEVINFO) man page says "All handles associated with this
snapshot become invalid after the call to di_fini()". But after that,
eight lines down, the subroutine was calling di_prop_lookup_ints with
a handle args.node which was stored from walking the device tree, and
then using the pointers that returned even further down.

New interfaces to map memory with MTRR (or similar) support.

Added new functions pci_device_map_range and pci_device_unmap_range to
handle mapping of PCI device BARs. These new interfaces allow the
possiblity of MTRRs on platforms that support them.

These additional APIs necessitated changing some internal interfaces. The
code for FreeBSD and Solaris has been updated but has not been compiled or
tested.

Old interfaces are marked deprecated and will eventually be removed.
