Debarshi Dutta 62c03dfaef gpu: nvgpu: add support for nvs control_fifo ...

Add a device node for management of nvs control fifo buffers for
scheduling domains. The current design consists of a master structure
struct nvgpu_nvs_domain_sched_ctrl for management of users as well
as control queues. Initially all users are added as non-exclusive users.

Subsequent changes will add support for IOCTLS to manage opening of
Send/Receive and Event buffers, querying characteristics etc.

In subsequent changes, a user that tries to open a Send/Receive queue
will first try to reserve itself as an exclusive user and only if that
succeeds can proceed with creation of both Send/Receive queues.

Exclusive users will be reset to non-exclusive users just before they
close their device node handle.
