[PATCH v2 0/4] drm/nvdla: Add driver support for NVDLA

[Cai Huoqing]

The NVIDIA Deep Learning Accelerator (NVDLA) is an open source IP
which is integrated into NVIDIA Jetson AGX Xavier,
so add driver support for this accelerator."

v1->v2:
*Rename nvdla_drm.[ch] to nvdla_drv.[ch] and rename nvdla_ioctl.h to nvdla_drm.h,
 move it to uapi.

*Remove the  onexistent filename  in Makefile

*Sort file names alphabetically in Makefile.
*Rearrange the error messages, and use drm_err/_dbg() instead of pr_err/_dbg().
*Replace  "dla_" prefix with "nvdla_"
*Check the iosys_map by iosys_map_is_null(), and check "ret" directly.
*Using iosys_map_memcpy_to/_from() for iosys_map instead of memcpy()
*Fix parameter error "dma_buf_vunmap(buf, ptr)", use "&map" instead of "ptr"
*Use iosys_map instead of kvaddr and use "iosys_map_set_vaddr()" to initialize iosys_map
*Using "vma->vm_pgoff -= drm_vma_node_start(&obj->vma_node)" to update vm_pgoff is cleaner
*Remove the unused nvdla_drm_gem_mmap, register drm_gem_mmap to file_operations directly.
*Use DEFINE_DRM_GEM_FOPS() to define nvdla_drm_fops.
*Remove the unused nvdla_drm_gem_mmap_buf, register drm_gem_prime_mmap to drm_driver directly.

*Fix typo and some code style
*Remove unused function nvdla_get_time_us()
