gpu: nvgpu: add characteristic flag for syncpoint address support

Add characteristic flag NVGPU_GPU_FLAGS_SUPPORT_SYNCPOINT_ADDRESS to indicate if
platform supports semaphore GPU_VA address for a syncpoint

Define NVGPU_SUPPORT_SYNCPOINT_ADDRESS for core driver book keeping

Set this flag for both GV100 and GV11B since Xavier SoC supports a semaphore
GPU_VA address for a syncpoint through syncpoint SHIM
