PATCH 1/1 ARM: mm: Fix dma_contiguous_reserve comment

DMA contiguous allocations have been able to use highmem since commit "95b0e65 ARM: mm: don't limit default CMA region only to low memory" but a comment still notes the earlier "low memory" limitation. Update the comment to remove the low memory limitation and fix the s/contigouos/contiguous/ typo while we're at it.

Hello,

DMA contiguous allocations have been able to use highmem since commit "95b0e65 ARM: mm: don't limit default CMA region only to low memory" but a comment still notes the earlier "low memory" limitation. Update the comment to remove the low memory limitation and fix the s/contigouos/contiguous/ typo while we're at it.
