Add User space API NVGPU_AS_IOCTL_GET_SYNC_RO_MAP to get read-only syncpoint
address map in user space
We already map whole syncpoint shim to each address space with base address
being vm->syncpt_ro_map_gpu_va
This new API exposes this base GPU_VA address of syncpoint map, and unit size
of each syncpoint to user space.
User space can then calculate address of each syncpoint as
syncpoint_address = base_gpu_va + (syncpoint_id * syncpoint_unit_size)
Note that this syncpoint address is read_only, and should be only used for
inserting semaphore acquires.
Adding semaphore release with this address would result in MMU_FAULT
Define new HAL g->ops.fifo.get_sync_ro_map and set this for all GPUs supported
on Xavier SoC

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
