Rajesh Shah 3fb02738b0 [PATCH] acpi bridge hotadd: Allow ACPI .add and .start operations to be done independently 
Create new interfaces to recursively add an acpi namespace object to the acpi
device list, and recursively start the namespace object.  This is needed for
ACPI based hotplug of a root bridge hierarchy where the add operation must be
performed first and the start operation must be performed separately after the
hot-plugged devices have been properly configured.
