Jianqun Xu 7a669a6418 mm: cma: add CmaAllocated/CmaReleased info for meminfo node 
Show the CMA pages used by cma_alloc in meminfo node.

Tested on RV1126 EVB DDR3:
CmaTotal:         270336 kB
CmaAllocated:      44408 kB
CmaReleased:      225928 kB
CmaFree:               0 kB

The CmaTotal = CmaAllocated + CmaReleased, and the CmaFree is pages
under cma area unused by system.

The CmaAllocated can be calculated by CMA_DEBUGFS.
Tested on RV1126 EVB DDR3:
cat /sys/kernel/debug/cma/*/used
10756
346

The results from cma used is in page count, 1 page = 4kByte
CmaAllocated = 44408kB = 10756 + 346 pages

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
