As seen on any other pinctrl subdriver that calls code from a main driver, each subdriver needs to have a different compatible string. We don't want the same compatible string to match a different subdriver's pinmux data as it's not for our SoC. Therefore, add new compatible strings for each pinctrl subdriver. Change driver name on all subdrivers accordingly.
