[PATCH v2] pinctrl: freescale: Add support for imx943 pinctrl

[Jacky Bai]

The i.MX943 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.MX943 IOMUXC Daisy input register differs from
that of the i.MX95. Update the pinctrl-imx-scmi driver to add support for
i.MX943.
