gpu: nvgpu: set GR tick frequency to max

Browse Source 
GR tick frequency needs to be set to MAX value for profiler
use cases for gp10b/gv11b/tu104 chips.

Add new HAL g->ops.ptimer.config_gr_tick_freq() that configures GR
tick frequency to MAX value and call this HAL in GPU poweron path.

This support is not needed in safety build, so compile everything
only if CONFIG_NVGPU_DEBUGGER is enabled
