gpu: nvgpu: Move Linux files away from common
Move all Linux source code files to drivers/gpu/nvgpu/os/linux from drivers/gpu/nvgpu/common/linux. This changes the meaning of common to be OS independent. JIRA NVGPU-598 JIRA NVGPU-601 Change-Id: Ib7f2a43d3688bb0d0b7dcc48469a6783fd988ce9 Signed-off-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1747714 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
