Store nvgpu_cdev pointer in struct tsg_private and assign it in nvgpu_ioctl_tsg_open. In gk20a_tsg_ioctl_bind_channel_ex(), extract gpu_instance_id from cdev pointer and then extract instance specific max VEID count from gpu_instance_id. Use this max veid count to validate subcontext id coming from user.
