gpu: nvgpu: Remove support for legacy mapping

Make NVGPU_AS_MAP_BUFFER_FLAGS_DIRECT_KIND_CTRL mandatory for all map
IOCTLs. We'll clean up the legacy kernel code in subsequent patches.

Remove support for NVGPU_AS_IOCTL_MAP_BUFFER. It has been superseded
by NVGPU_AS_IOCTL_MAP_BUFFER_EX.

Remove legacy definitions to nvgpu_map_buffer_args and the related
flags, and update the in-kernel map calls accordingly by switching to
the newer definitions.
