[PATCH RFC 1/5] ACPI / containers : add support for ACPI0010 processor container

[Sudeep Holla]

ACPI 6.0 adds support for optional processor container device which may
contain child objects that are either processor devices or other processor
containers. This allows representing hierarchical processor topologies.

It is declared using the _HID of ACPI0010. It may also have _CID of
PNP0A05, which represents a generic container device.

This patch enables the support for these ACPI processor containers.
