[PATCH] arm64: Change misleading function names in dma-mapping

[Ritesh Harjani]

From: Ritesh Harjani <ritesh.harjani at gmail.com>

arm64_swiotlb_alloc/free_coherent name can be misleading
somtimes with CMA support being enabled after this
patch (c2104debc235b745265b64d610237a6833fd53)

Change this name to be more generic:
__dma_alloc/free_coherent
