mm: cma: fix totalcma_pages to include DT defined CMA regions

Browse source 
The totalcma_pages variable is not updated to account for CMA regions
defined via device tree reserved-memory sub-nodes.  Fix this omission by
moving the calculation of totalcma_pages into cma_init_reserved_mem()
instead of cma_declare_contiguous() such that it will include reserved
memory used by all CMA regions.
