This commit introduces a new interrupt controller driver used
for NXP's IRQ_STEER IP.
Apart from introducing the driver itself, this commit contains
the following changes:
1) Switch i.MX8MP to using the XTENSA core interrupt
controller instead of the dummy irqsteer one.
* this is required because the binding for the
irqsteer driver is no longer a dummy one
(since it's being used by the irqsteer driver).
As such, to avoid having problems, switch to
using another dummy binding.
2) Modify the irqsteer dummy binding such that it
serves the IRQ_STEER driver's needs.

Add dummy interrupt id until we can support UART interuppt
on i.MX8MP in order to fix compilation warnings.

Remove nxp,imx-mu-rev2 compatible. This IP block is the same as the
nxp,imx-mu device, and should be handled by the same compatible
Instead, use CONFIG_HAS_MCUX to determine which HAL APIs should be used
to interact with the messaging unit IP.

Add mailbox and interrupt-controller nodes used for
inter-process communication.
Add also the dt binding for the interrupt-controller.
For now, this is used just to fix some compile errors,
since the mailbox requires an interrupt-controller.
For DSP, we have a direct interrupt line to the core.

Enable UART on the DSP from the i.MX8MP target:
- add corresponding nodes in dtsi and dts;
- create a dts overlay for uart;
- add a config fragment for uart and console configuration.
So, in order to compile an application and enable UART
a user must run west build using DTC_OVERLAY_FILE and CONF_FILE.
Here's an example for hello_world:
west build -p always -b nxp_adsp_imx8m samples/hello_world/
-DDTC_OVERLAY_FILE="boards/xtensa/nxp_adsp_imx8m/
nxp_adsp_imx8m_uart.overlay" -DCONF_FILE="boards/xtensa/nxp_adsp_imx8m/
nxp_adsp_imx8m_uart.conf"
For other applications, like SOF, where we don't need UART, we simply run:
west build -p always -b nxp_adsp_imx8m ../modules/audio/sof/ --
-DTOOLCHAIN=/opt/zephyr-sdk-0.15.2/xtensa-nxp_imx8m_adsp_zephyr-elf/
bin/xtensa-nxp_imx8m_adsp_zephyr-elf -DINIT_CONFIG=imx8m_defconfig
The nxp_adsp_imx8m is using the nxp_imx_iuart driver.
For now, is used in poll mode.
Next step is to enable the interrupt controller in
DSP and use the interrupt driver UART.

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.MX8MP board.
This has one HiFi4 core, from Cadence, lx6 compatible
and 2 System RAM.
