gpu: nvgpu: Add support for new output type in VFE table

Browse Source 
Changes:
1. Added a new type: CTRL_PERF_VFE_EQU_OUTPUT_TYPE_THRESHOLD
   This parameter was added in VFE table(under index 36) of 4F VBIOS to 
   convert VFE floating point output into threshold percentage value for 
   Fmon threshold programming.
