mem: add function for setting DMA mask

This patch adds the possibility of setting a dma mask to be used
once the memory initialization is done.

This is currently needed when IOVA mode is set by PCI related
code and an x86 IOMMU hardware unit is present. Current code calls
rte_mem_check_dma_mask but it is wrong to do so at that point
because the memory has not been initialized yet.
