gpu: nvgpu: gv10x volt policy boardobj changes

- Added support for single rail multi step volt policy & below
  are the list of define & struct added/updated to support same.
   CTRL_VOLT_POLICY_TYPE_SINGLE_RAIL_MULTI_STEP 0x04,
   NV_VBIOS_VOLTAGE_POLICY_1X_ENTRY_TYPE_SINGLE_RAIL_MULTI_STEP 0x04,
   Updated struct vbios_voltage_policy_table_1x_entry,
   struct nv_pmu_volt_volt_policy_sr_multi_step_boardobj_set, this holds
     members which help to config single rail multi step like delay
     between switch step, ramp up & ramp down step size in uv.
- Added case to support SINGLE_RAIL_MULTI_STEP in
  volt_volt_policy_construct() based on boardobj type.
- Added case to support SINGLE_RAIL_MULTI_STEP in
  volt_get_volt_policy_table() to read data from VBIOS
  table vbios_voltage_policy_table_1x_entry & extract to
  voltage_policy_single_rail_multi_step.
- Added methods to forward single rail multi step data to
  PMU using below methods by assigning data read from
  VBIOS voltage_policy_single_rail_multi_step to
  nv_pmu_volt_volt_policy_sr_multi_step_boardobj_set
  interface.
    volt_construct_volt_policy_single_rail_multi_step()
    volt_policy_pmu_data_init_sr_multi_step()
    volt_policy_pmu_data_init_single_rail()
    construct_volt_policy_single_rail()
