Defines device tree aliases for on-chip peripherals at the soc level
instead of the board level for all i.mx 6/7 socs. The eliminates some
duplicate code in the board level device trees, and will allow drivers
to use device-tree generated macros directly instead of through dts
fixups.

On i.mx6/7 the TCMU and TCML regions are specific to instruction or
data. So use the nxp,imx-itcm for TCML and nxp,imx-dtcm for TCMU.

Newer DTC now warns about mismatch between the reg and unit-address.
Most of these cases are due to case not matching, so fix thoses so
everything is lowercase.

This patch adds the RDC (Resource Domain Controller) peripheral
permissions settings for the i.MX applications cores (Cortex A9 on
i.MX6 and Cortex A7 on i.MX7).
This will enable both Linux (on application's core) and Zephyr (on M4
core) to share the peripherals and coexist.
The settings are defined at devicetree level and applied in the soc.c.
A complete solution should involve the SEMA4 to control the peripherals
access and prevent resource deadlocking and misusage.

The i.MX 6SoloX SoC is a hybrid multi-core processor composed by one
Cortex A9 core and one Cortex M4 core.
Zephyr was ported to run on the M4 core. In a later release, it will
also communicate with the A9 core (running Linux) via RPMsg.
The low level drivers come from NXP FreeRTOS BSP and are located at
ext/hal/nxp/imx. More details can be found at ext/hal/nxp/imx/README
The A9 core is responsible to load the M4 binary application into the
RAM, put the M4 in reset, set the M4 Program Counter and Stack Pointer,
and get the M4 out of reset.
The A9 can perform these steps at bootloader level after the Linux
system has booted.
