[PATCH v2 03/32] scripts/cocci: Rename memory-region-{init-ram -> housekeeping}

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

As we are going to add various semantic changes related to the memory
region API, rename this script to be more generic.
Add a 'usage' header, and an entry in MAINTAINERS to avoid checkpatch
warning.
