pinctrl: imx: Add support for NXP i.MX952
The i.MX952 System Manager (SM) firmware supports the System Control
Management Interface (SCMI) pinctrl protocol, similar to the i.MX95 SM.
The base offset for the i.MX952 IOMUXC Daisy input register differs from
that of the i.MX95. Update the pinctrl-imx-scmi driver to add support for
i.MX952.
