ARM SCMI v3.2 Table 24 Pin Configuration Type and Enumerations:
'192 -255 OEM specific units'.

i.MX95 System Manager FW supports SCMI PINCTRL protocol, but uses
OEM Pin Configuration type, so extend the driver to support custom
params.

The node will be as below:
pinctrl_usdhc1: usdhc1-pins {
	sd1cmd {  ==> this is needed, so there is a patterProperties in nxp,imx95-scmi-pinctrl.yaml
		pins = "sd1cmd";
		nxp,func-id = <0>;
		nxp,pin-conf = <0x138e>;
	};
	sd1data {
		pins = "sd1data";
		nxp,func-id = <0>;
		nxp,pin-conf = <0x138e>;
	};
};

This patchset depends on [1].

Changes in v2:
- Rename nxp,imx95-pinctrl.yaml  to nxp,imx95-scmi-pinctrl.yaml and move
  to firmware
- Merged patch [1,2]/3 v1 into patch 1/2 v2.
- nxp,imx95-scmi-pinctrl.yaml only has patterProperties for subnode
  The pinctrl will be as below for i.MX95.
	pinctrl_usdhc1: usdhc1-pins {
		sd1cmd {
			pins = "sd1cmd";
			nxp,func-id = <0>;
			nxp,pin-conf = <0x138e>;
		};
		sd1data {
			pins = "sd1data";
			nxp,func-id = <0>;
			nxp,pin-conf = <0x138e>;
		};
	};
- Add pins enum, correct description.
- Link to v1: https://lore.kernel.org/r/20240412-pinctrl-scmi-oem-v1-v1-0-704f242544c1@nxp.com
