- Change contigmalloc() to use the vm_paddr_t type instead of an unsigned
long for specifying a boundary constraint.
- Change bus_dma tags to use bus_addr_t instead of bus_size_t for boundary
constraints.

These allow boundary constraints to be fully expressed for cases where
sizeof(bus_addr_t) != sizeof(bus_size_t). Specifically, it allows a
driver to properly specify a 4GB boundary in a PAE kernel.

Note that this cannot be safely MFC'd without a lot of compat shims due
to KBI changes, so I do not intend to merge it.

- There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
(bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
since r52045) but even recently added device drivers do this unnecessarily.
Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.

- Also while at it, use __FBSDID.

Use 4 KB pages for storage bus devices, which seems to be what the HV uses
internally.

This is more complicated than I expected. Storage devices need the IOMMU
set up, but must not use it.

The IOMMU is not involved for the storage bus.

Driver for PS3's internal hard disk. Hopefully this can be CAM-ified in
the future, but presents a set of simple block devices for now. With
(forthcoming) boot loader support or vfs.root.mountfrom, allows booting
PS3s from disk.

Add RTC support for the LV1 clock on the PS3. The hypervisor won't let us
set it, but it's better than nothing.

Import support for the Sony Playstation 3 using the OtherOS feature
available on firmwares 3.15 and earlier.

Caveats: Support for the internal SATA controller is currently missing,
as is support for framebuffer resolutions other than 720x480. These
deficiencies will be remedied soon.

Special thanks to Peter Grehan for providing the hardware that made this
port possible, and thanks to Geoff Levand of Sony Computer Entertainment
for advice on the LV1 hypervisor.
