[PATCH 01/16] drm/amd/display: Remove NonUrgentLatencyTolerance VBA variable

[Maíra Canal]

The NonUrgentLatencyTolerance variable from the struct vba_vars_st is
only used on assignments, so its value is not used on code. Moreover,
its getter function is not used also. So, remove the
NonUrgentLatencyTolerance entry from the struct vba_vars_st.
