Add minimal DTS support for the m2gl025_miv. The dts just has the core,
SoC, PLIC, and UART described. We still get memory related info from
Kconfig.

The 'id' field was never used and tended to just have the compat of the
node. Lets remove it and removed some code in extract_dts_includes.py
related to it. Added a warning if 'id' is set in a yaml so we can
remove it going forward.

Added basic PSoC6 UART driver and added two UART nodes in the PSoC6
device tree to have output from CM0+ and CM4 cores.

Add 'generation: define' directive to 'compatible' property.
When existing for a type of device, move compatible property

UART pins (TX, RX, RTS, CTS) are now configured in DTS files.
RTS and CTS definitions are optional. If flow control is enabled
and RTS/CTS pins are not defined, then compiler will issue
an error message.

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.

After running some tests which enable assert macro I found some issues
with the i.MX UART configuration.
This patch configures the Tx Fifo Watermark and Modem Mode accordingly.

The common uart.yaml defines an optional clocks property that can be
overridden by specific serial driver bindings to be required. The
description and generation attributes are duplicated.
This fixes build warnings:
extract_dts_includes.py: Merge of 'description': 'Clock gate control
information' overwrites 'Clock gate information'.
extract_dts_includes.py: Merge of 'generation': 'structures' overwrites
'define'.
And introduces a different build warning, which is intended behavior:
extract_dts_includes.py: Merge of 'category': 'required' overwrites
'optional'.

LPUART (Low-power UART) peripheral is just like ordinary U(S)ART
which lives in a separate clock/power domain.
Therefore already existing code could be reused as is
almost entirely.

Adds a shim layer around the imx uart driver to adapt it to the Zephyr
serial interface.
Modem mode was introduce to control it as DCE and DTE and can be
configured in the device tree:
modem-mode:
type: int
category: required
description: Set the UART Port to modem mode 0 (dce) 1 (dte)
generation: define
For now only the UART 2 was tested.

Add usart-yaml in dts.

Only polling mode is implemented in usart now. Interrupt can be added in
future.

According to yaml syntaxic rules, 'properties' described in dts
bindings yaml files could be seen as 'mapping'(key/value couple),
instead of 'series' (list of single elements).
yaml 'mappings' will then be converted by yaml python library as
python 'dict' which will ease treatment (instead of current list
as were before this commit).
Same treatment is applied to 'inherits'.
script extract_dts_inlcude is updated to take change of yaml_list
structre into account. This allows some code simplification. Largest
impact is yaml_collapse function which works now allow complete
overload method on all the attributes of a yaml nodes.
