Joonsoo Kim d883c6cf3b Revert "mm/cma: manage the memory of the CMA area by using the ZONE_MOVABLE" 
This reverts the following commits that change CMA design in MM.

 3d2054ad8c ("ARM: CMA: avoid double mapping to the CMA area if CONFIG_HIGHMEM=y")

 1d47a3ec09 ("mm/cma: remove ALLOC_CMA")

 bad8c6c0b1 ("mm/cma: manage the memory of the CMA area by using the ZONE_MOVABLE")

Ville reported a following error on i386.

The reason for this error is that the span of MOVABLE_ZONE is extended
to whole node span for future CMA initialization, and, normal memory is
wrongly freed here.  I submitted the fix and it seems to work, but,
another problem happened.

It's so late time to fix the later problem so I decide to reverting the
series.
