Nicolin Chen a8e6d13652 gpu: nvgpu: Delete NVGPU_DMA_FORCE_CONTIGUOUS ...

The flag NVGPU_DMA_FORCE_CONTIGUOUS simply means that the memory
or the pages should be forced contiguous. Meanwhile, the other
flag NVGPU_DMA_PHYSICALLY_ADDRESSED means that the memory should
be contiguous from GPU perspective, either physically contiguous
when IOMMU is not used, or virtually contiguous by IOMMU.

Thus the NVGPU_DMA_FORCE_CONTIGUOUS flag is now redundant.

This patch cleans up the NVGPU_DMA_FORCE_CONTIGUOUS flag.
