[v4,00/15] arm64: dts: imx8: architecture improvement and adding imx8qm support

Message

IMX SCU based platforms (e.g. MX8QM/MX8QXP) are comprised of a number of SS
(Subsystems), those SS may be shared between different SoCs while most of them
can be reused like Devices Resources, Clocks, Power domains and etc.

This patch series aims to improve the MX8 architecture to comply with the HW
design to save a lot of duplicated codes and benefits us a better
maintainability and scalability in the future.

ChangeLog:
v3->v4:
 * mainly rebase to latest kernel except a few very minor changes like change to use
   new scu protocol binding which was not supported in last version
v2->v3:
 * use clock-indices property instead of bit-offset property suggested by Shawn Guo
 * rebase to latest shawn/for-next
v1->v2:
 * change to the new two cells scu clock binding, so original adding scu clocks
   patches were removed.
 * Move scu pd node above clk node
