[PATCH v2 2/3] clk: imx8mn: add SNVS clock to clock tree

[Horia Geantă]

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.

[PATCH v2 3/3] arm64: dts: imx8mn: add clock for snvs rtc node

[Horia Geantă]

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.
