From: Guanhua Gao <guanhua.gao@nxp.com>

Set DMA mask and coherent DMA mask to enable 64-bit addressing.

Notes:
    change from v2 to v3
    - remove check return value of dma_set_mask_and_coherent. 64bit mask always
    return success.
    - remove redundate comments
    change from v1 to v2
    - Remove 32bit DMA mask set.
