* DESCRIPTION: Install a handler for all op_regions of a given space_id.
*
* NOTE: This function should only be called after acpi_enable_subsystem has
* been called. This is because any _REG methods associated with the Space ID
* are executed here, and these methods can only be safely executed after
* the default handlers have been installed and the hardware has been
* initialized (via acpi_enable_subsystem.)
