There are already some boards that need these configs, for example, the
NXP i.MX95 19x19 EVK. For booting, the only one needed is
CONFIG_PINCTRL_IMX_SCMI for the scmi_iomuxc pinctrl driver. Regarding
the other configs, they enable Ethernet and PCIe for now. All configs
are on imx95.dtsi.

I will prepare a v2 rephrasing the commit message.
