[0/4] clk: imx: scu: add parsing clocks from device tree support

This patch series is a preparation for the MX8 Architecture improvement.
As for IMX SCU based platforms like MX8QM and MX8QXP, they are comprised
of a couple of SS(Subsystems) while most of them within the same SS
can be shared. e.g. Clocks, Devices and etc.

However, current device tree is heavily depends on Clocks IDs defined which
cause some troubles in writing the common <soc>-ss-xx.dtsi file.

This patch series adds a new binding to support parsing clocks from device tree
which can fully decouple the dependency of Clock IDs in device tree.
This can make the clock driver much easily to be maintained in the future and
avoid writing a lot of duplicated codes.
