mm: add cma pcp list
Add a cma pcp list in order to increase cma memory utilization.
Increased cma memory utilization will improve overall memory
utilization because free cma pages are ignored when memory reclaim
is done with gfp mask GFP_KERNEL.
Since most memory reclaim is done by kswapd, which uses a gfp mask
of GFP_KERNEL, by increasing cma memory utilization we are therefore
ensuring that less aggressive memory reclaim takes place.
Increased cma memory utilization will improve performance,
for example it will increase app concurrency.
