i.mx8mn has support for clock gating the snvs module.
Add it into clock tree so that rtc-snvs driver could use it.
Note this will also be required in the snvs_pwrkey driver,
once support for clock management will be added.

Initial commit adding imx8mn support:
6c3debcbae47 ("arm64: dts: freescale: Add i.MX8MN dtsi support")
added the "clock-names" property for the snvs rtc node,
however it missed adding the clock.
