src/sys/dev/acpi: acpi.c acpi_util.c acpi_util.h
Use the new ACPICA functions AcpiAttachData() and AcpiGetData() to associate
all "struct acpi_devnodes" to their corresponding ACPI_HANDLEs. Anywhere in
the acpi(4) subtree, the node-structure can be obtained from a handle via
acpi_get_node(). The idea is similar to e.g. device_private().
Benefits: (a) simplifies code, (b) avoids issues with locking as ACPICA does
the serialization for us, (c) avoids the need to access the glocal softc, and
(d) avoids the O(n) loop required to search for a handle from the node queue.
