a39c48e3e2 gpu: nvgpu: MISRA 14.4 err/ret/status as boolean
MISRA rule 14.4 doesn't allow the usage of integer types as booleans
in the controlling expression of an if statement or an iteration
statement.

Fix violations where the integer variables err, ret, status are used
as booleans in the controlling expression of if and loop statements.

3c3f80a687 gpu: nvgpu: MISRA Rule 21.2 header guard fixes
MISRA rule 21.2 doesn't allow the use of macro names which start with
an underscore. These leading underscores are to be removed from the
macro names. This patch will fix such violations in nvgpu by
renaming them to follow the convention,'NVGPU_PARENT-DIR_HEADER-NAME'
when there is no keyword repetition between file name and directory
or 'NVGPU_HEADER-NAME' when there is repetition.

d3f96dfa96 gpu: nvgpu: gv10x volt rail boardobj changes
- Created volt ops under pmu_ver to support volt_set_voltage,
  volt_get_voltage & volt_send_load_cmd_to_pmu.
- Renamed volt load, set_voltage & get_voltage gp10x method names.
- Added new volt load, set_voltage & get_voltage methods for gv10x
  using RPC & added code to handle ack in pmu_rpc_handler() along
  with struct rail_list changes.
- Updated volt ops of gp106 & gv100 to point to respective methods.
- Added member volt_dev_idx_ipc_vmin & volt_scale_exp_pwr_equ_idx to
  "struct nv_pmu_volt_volt_rail_boardobj_set" & "struct voltage_rail"
  made changes to update members as needed.
- Added member volt_scale_exp_pwr_equ_idx to
  "struct vbios_voltage_rail_table_1x_entry" to read
  value from VBIOS table & update rail boardobj set interface.
- Defines for volt RPC "NV_PMU_RPC_ID_VOLT_*"
- Define struct's volt load, set_voltage & get_voltage to execute
   volt RPC.
