Use a similar model to the pinmux_rv32m1 driver for kinetis pinmux driver. We handle one subtle difference between clock on the KE1xF v other SoCs. As the Kconfig and devicetree label names are the same we maintain the Kconfig options in the driver until all board users are converted over to use devicetree instead of Kconfig.
