Some devices may belong to >1 power domain, so with the current design
this is something not possible to describe. It's worth to note that
Linux also uses the `power-domains` naming scheme, not `power-domain`.
This patch also introduces `power-domain-names` so that each entry in
`power-domains` can be given a name if needed. `#power-domain-cells`
is now required as well.

Add mailbox node used for inter-process communication.
For DSP, we have a direct interrupt line to the core.

Since the LPUART peripheral DTS binding requires the
"interrupts" property be specified even if it's not going
to be used for now we need to add a dummy interrupt controller
node to make that possible. Logically speaking, this dummy
interrupt controller should be used by peripherals which
can assert interrupts directly routed to the DSP.

This commit enables clock control on the i.MX8QM and QXP boards.
This is achieved through the following changes:
1) The "reg" property is no longer marked as required
for the "nxp,imx-ccm" binding. This is necessary because
in the case of i.MX8QM and i.MX8QXP the clock management
is done through the SCFW, hence there's no need to access
CCM's MMIO space (not that you could anyways).
2) The DTS now contains a scu_mu node. This node refers
to the MU instance used by the DSP to communicate with
the SCFW.
3) The CCM driver needs to support the LPUART clocks
(which will be the only IP that's supported for now)
and needs to perform an initialization so that the
NXP HAL driver knows which MU to use to communicate
with the SCFW.

In order to bring consistency in-tree, migrate all dts code to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to zephyrproject-rtos#45388 for more details.

Add dtsi file for i.MX8QM and i.MX8QXP boards.
These two have the same board-level definitions,
so we call it, generically, imx8.
