tkudav c6e021589e gpu: nvgpu: PS3.5 VFE VAR and EQU changes
Changes between GV100 and Turing VFE pstate tables-
1. PS3.5 ucode packs two sets of vfe boardobjgrp - primary and
   rppm in new struct whose name is appended with suffix pack. The
   rppm (runtime power and performance model) set is needed to
   achieve Max Q. The rppm set is not relevant to Automotive SKUs and
   entries are set to 'disabled'. But the turing ucode in R400 uses
   the 'pack' struct to calculate supersurface offset and size of
   vfe_var/equ boardobjgrp.
2. Header size has been increased to add RPPM related VFE variable
   and equation count.

VFE Variables boardobjgrp specific changes-
1. New var type 'single caller specified' had been added to represent
   generic type of variable which is not associated with voltage or
   frequency but identified by a Unique ID.
2. The frequency variable type can be associated with a clock domain,
   if the clock domain index availability flag is set.

VFE Equations boardobjgrp specific changes-
1. New entry type 'scalar' had been added to allow scaling equation
   pointed by 'equ_idx_to_scale'.
2. More ouput types are added to represent the equation evaluation
   results.

We modify the nvgpu Turing driver and GV100 ucode to adapt to these
changes.
This patch also fixes some MISRA defects in touched files.
