Seema Khowala 982fcfa737 gpu: nvgpu: Add timeouts_disabled_refcount for enabling timeout ...

-timeouts will be enabled only when timeouts_disabled_refcount
 will reach 0
-timeouts_enabled debugfs will change from u32 type to file type
 to avoid race enabling/disabling timeout from debugfs and ioctl
-unify setting timeouts_enabled from debugfs and ioctl
