- 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.
Discussed with: jhb
- Also while at it, use __FBSDID.

Add support to ACPI to manage its own resources. Previously, resource
allocation was passed up to nexus. Now, we probe sysresource objects and
manage the resources they describe in a local rman pool. This helps
devices which attach/detach varying resources (like the _CST object) and
module loads/unloads. The allocation/release routines now check to see if
the resource is described in a child sysresource object and if so,
allocate from the local rman. Sysresource objects add their resources to
the pool and reserve them upon boot. This means sysresources need to be
probed before other ACPI devices.
Changes include:
* Add ordering to the child device probe. The current order is: system
resource objects, embedded controllers, then everything else.
* Make acpi_MatchHid take a handle instead of a device_t arg.
* Replace acpi_{get,set}_resource with the generic equivalents.
