When CM4 image needs to be loaded from Linux userspace, we need
power on CM4 CORE, MU_1A and etc. Then start CM4 CORE.
Because we need to add multilple power domains, default power
domain attach probe only support one power domain,
we get the power domain in probe and mark on.
We are lucky that the TCML space could be accessed even without
power on the resources, so it is ok power on in probe. If not,
elf load will not be able to load segments to TCML.

i.MX8QXP support hardware partition feature, the M4
could be controlled by System Control Unit(SCU). The M4 is out
of control of Linux with hardware partition used which is the normal
case for production in automotive space.
When M4 reboot, SCU will issue interrupt to Linux side, and Linux side
will recovery the connection. To use related functions, guard code
with CONFIG_IMX_SCU which is enabled for all i.MX SoCs with SCU inside.
Currently we only support IPC only case for i.MX8QXP.
