- 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.
