[V3,5/5] clk: imx: scu: add fallback compatible string support

Commit Message

SCU clock can be used in a similar way by IMX8QXP and IMX8QM SoCs.
Make the driver support "fsl,scu-clk" fallback compatible string
to allow other SoCs to reuse the common part.

Hi Stephen,

Can you help picked this one?
SCU clock is likely to be common, so we add a common
compatible string to handle it.

BTW Patch 1~2 already picked up by Shawn.
Patch 3~4 dropped.

Regards
Dong Aisheng
