gpu: nvgpu: move vgpu code to linux
Most of VGPU code is linux specific but lies in common code So until VGPU code is properly abstracted and made os-independent, move all of VGPU code to linux specific directory Handle corresponding Makefile changes Update all #includes to reflect new paths Add GPL license to newly added linux files Jira NVGPU-387 Change-Id: Ic133e4c80e570bcc273f0dacf45283fefd678923 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1599472 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
