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