MGS-2719 [#imx-421] fix gckOS_MapMemory failure

gckOS_MapMemory failure with 4.9 kernel on ARM64 build,

_DmaMapUser will return gcvSTATUS_OUT_OF_MEMORY since
dma_mmap_writecombine does not set the valid device handle.

fslcma allocator has the same function as the DMA allocator,
then disable the DMA allocator to avoid more problems.
