pinctrl: nxp: imx9: Guard pinctrl match table with CONFIG_IMX9[X]

The i.MX9 pinctrl match table currently lists all SoC compatibles
unconditionally, which may lead to unused entries being included when
building for specific SoC variants. Guard each compatible entry with
the corresponding CONFIG_IMX9[X] option so only the required SoC
entries are compiled in, which reduces unnecessary data.
