This is a big cleanup of return types across a number of modules in the
nvgpu driver. Many functions were returning u32 but using negative
return codes. This is a MISRA 10.3 violation by assigning signed values
to a u32.

- 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()

- changes to read voltage tables from VBIOS
& create boardobj then send to pmu
- Rail, Device & Policy objects are read from VBIOS & created boardobjs
- RPC support to load, Set & get voltage.
