Patrick Delaunay 55b0affd26 firmware: scmi: use protocol node name to bind the scmi regulator driver 
In scmi firmware driver, it is better to bind the scmi protocol driver
"scmi_voltage_domain" with the node name of the protocol 17 and not
the sub-node named "regulator", because is a fixed string which doesn't
provide information and because it is not aligned with the other scmi
protocol nodes.

For example on stm32mp135f-dk board with device tree in stm32mp131.dtsi

scmi: scmi {
	compatible = "linaro,scmi-optee";
	#address-cells = <1>;
	#size-cells = <0>;
	linaro,optee-channel-id = <0>;
	shmem = <&scmi_shm>;
	scmi_clk: protocol@14 {
		reg = <0x14>;
		#clock-cells = <1>;
	};
	scmi_reset: protocol@16 {
		reg = <0x16>;
		#reset-cells = <1>;
	};
	scmi_voltd: protocol@17 {
		reg = <0x17>;
		scmi_regu: regulators {
			#address-cells = <1>;
			#size-cells = <0>;
			scmi_reg11: voltd-reg11 {
				reg = <VOLTD_SCMI_REG11>;
				regulator-name = "reg11";
			};
			scmi_reg18: voltd-reg18 {
				reg = <VOLTD_SCMI_REG18>;
				regulator-name = "reg18";
			};
			scmi_usb33: voltd-usb33 {
				reg = <VOLTD_SCMI_USB33>;
				regulator-name = "usb33";
			};
		};
	};
};

Before the patch:

 regulator     2  [ + ]   scmi_regulator        |       |-- voltd-usb33
