Added implementation for following IOCTLs NVGPU_NVS_CTRL_FIFO_CREATE_QUEUE NVGPU_NVS_CTRL_FIFO_RELEASE_QUEUE The above ioctls are supported only for users with R/W permissions. 1) NVGPU_NVS_CTRL_FIFO_CREATE_QUEUE constructs a memory region via the nvgpu_dma_alloc_sys() API and creates the corresponding GPU and kernel mappings. Upon successful creation, KMD exports this buffer to the userspace via a dmabuf fd that the UMD can use to mmap it into its process address space. 2) Added plumbing to store VMA's corresponding to different users for event queue in future. 3) Added necessary validation checks for the IOCTLs 4) NVGPU_NVS_CTRL_FIFO_RELEASE_QUEUE is used to clear the queues. 5) Using a global queue lock to protect access to the queues. This could be modified to be more fine-grained in future when there is more clarity on GSP's implementation and access of queues. 6) Added plumbing to enable user subscription to queues. NVGPU_NVS_CTRL_FIFO_RELEASE_QUEUE is used to unsubscribe the user from the queue. Once, the last user is deleted, all the queues will be cleared. User must ensure that any mappings are removed before calling release queue. 7) Set the default queue_size for event queues to PAGE_SIZE. This can be modified later. For event queues, UMD shall fetch the queue_size.
