Hal API g->ops.gr.halt_pipe() is defined in unsafe unit hal.gr.gr
It is called from safe unit, and it calls into API
g->ops.gr.falcon.ctrl_ctxsw() which is also safe
Hence get rid of unsafe API g->ops.gr.halt_pipe().
Caller now directly calls hal.gr.falcon API to halt pipe

like rbtree, enabled, string, etc go here. This helps prevent clutter

Support is enabled for TU104 with NVGPU_SUPPORT_DGPU_THERMAL_ALERT flag.
Board specific config is added in DT which will be parsed by nvgpu.
Nvgpu does the following.
1.Read gpio line number, interrupt type, and event delay from DT.
2.Call kernel methods and register the interrupt with kernel.
3.Create work queue which will process the interrupt in process context.
4.When interrupt occurs disable interrupt, add work to work queue.
5.In work queue post events and sleep for delay time then enable
