gpu: nvgpu: Use nvgpu_alloc_vid_at for dGPU ACR

ACR allocates buffers from vidmem and passes explicitly flag
NVGPU_DMA_NO_KERNEL_MAPPING. Vidmem buffers are never mapped to CPU,
and dGPU ACR does not actually care, so switch to using
nvgpu_alloc_vid_at(). This removes another explicit dependency
to NVGPU_DMA_NO_KERNEL_MAPPING, which is going to be removed.
