docs: admin-guide: add a series of orphaned documents

There are lots of documents that belong to the admin-guide but
are on random places (most under Documentation root dir).

Move them to the admin guide.

-=====================
-CMA Debugfs Interface
-=====================
-
-The CMA debugfs interface is useful to retrieve basic information out of the
-different CMA areas and to test allocation/release in each of the areas.
-
-Each CMA zone represents a directory under <debugfs>/cma/, indexed by the
-kernel's CMA index. So the first CMA zone would be:
-
-	<debugfs>/cma/cma-0
-
-The structure of the files created under that directory is as follows:
-
- - [RO] base_pfn: The base PFN (Page Frame Number) of the zone.
- - [RO] count: Amount of memory in the CMA area.
- - [RO] order_per_bit: Order of pages represented by one bit.
- - [RO] bitmap: The bitmap of page states in the zone.
- - [WO] alloc: Allocate N pages from that CMA area. For example::
-
-	echo 5 > <debugfs>/cma/cma-2/alloc
-
-would try to allocate 5 pages from the cma-2 area.
-
- - [WO] free: Free N pages from that CMA area, similar to the above.
