gpu: nvgpu: add conversion function for gpu alarm events

In order to enable the movement of clk arbitrator to common
code, we need to remove the NVGPU_GPU_EVENT_* defines (which
are present in uapi) and instead use the common code defines.
Add a conversion function for the same.
With this the uapi header is no longer required to be included
inside clk_arb.c
