ARM: mm: don't limit default CMA region only to low memory
ARM: mm: don't limit default CMA region only to low memory

DMA-mapping supports CMA regions places either in low or high memory, so
there is no longer needed to limit default CMA regions only to low memory.
 The real limit is still defined by architecture specific DMA limit.
