boards/arm: add support for imx95-evk m7 core

Browse source 
- Add support for the IMX95LPD5EVK-19 evaluation kit (M7 core only)
- Firmware can be executed from ITCM, DDR or NOR flash
- configurations:
  'nsh'   A minimal configuration that only enables nsh shell
          on a UART
  'rpmsg' This configuration is similar to nsh but in addition
	  it offers the Remote Processing Messaging (RPMsg) service to
	  enable heterogeneous inter-core communication.

===============
IMX95LPD5EVK-19
===============
The IMX95LPD5EVK-19 board is a platform designed to show the most commonly
used features of the i.MX 95 automotive applications processor.
Features
========
- Multicore Processing [1]_
- 1x Arm Cortex-M7
- 6x Arm Cortex-A55 multicore complex
- 1x Arm Cortex-M33
- Memory
- On-Chip Memory
- 1376kB SRAM (ECC)
- External Memory
- Up to 6.4GT/s x32 LPDDR5/LPDDR4X (with Inline ECC & Inline Encrpytion)
- 1x Octal SPI, including support for SPI NOR and SPI NAND memories
- Connectivity
- CAN FD
- UART/USART/Profibus, I²C, SPI
- Messaging Units (MU) to support IPC between heterogeneous cores
.. [1] NuttX is currently supported exclusively on the Cortex-M7 core of the
i.MX95
Serial Console
==============
The IMX95LPD5EVK-19 board features a high-speed USB-to-UART/MPSSE device,
FT4232H (U70) that provides a debug interface for the i.MX95 processor through
the USB type-C connector (J31). The device acts as a bridge to enable
communication between the target processor and the host computer, which
connects to the USB connector (J31) through a USB cable.
Channel A is used as UART port to provide USB-to-UART option for debugging the
Arm Cortex-M7 core of the i.MX 95 processor (default option).
J-Link External Debug Probe
===========================
The IMX95LPD5EVK-19 board provides a 2x5-pin Samtec FTSH-105-01-L-DV-K header
(J30) for connecting a JTAG debugger (external JTAG) for debugging the i.MX95
processor. The FT4234H JTAG provides the remote debug option for the i.MX95
processor.
Configurations
==============
nsh
---
Configures the NuttShell (nsh) located at examples/nsh. This NSH
configuration is focused on low level, command-line driver testing. Built-in
applications are supported, but none are enabled. This configuration does not
support a network.
This configuration can be used in combination with the default sd-card image
that is shipped with the EVK.
rpmsg
-----
This configuration is similar to nsh but in addition it offers the Remote
Processing Messaging (RPMsg) service to enable heterogeneous inter-core
communication. A virtual UART (CONFIG_RPMSG_UART) is made available on which
an OS running on the A55 cores can connect. There is also an option to use
the filesystem client feature in which a remote directory can be mounted to
a local directory (CONFIG_FS_RPMSGFS).
The rpmsg configuration executes the code from DDR since its code memory
footprint is bigger than the ITCM size. In the case of using the default
sd-card image from the EVK, adaptations are needed on the software running on
the M33 and A55 cores.
- `System Manager <https://github.com/nxp-imx/imx-sm>`_ (M33) should give
the M7 access to the DDR region
- `linux-imx <https://github.com/nxp-imx/linux-imx>`_ (A55) should reserve
the DDR region by specifying it in the device tree so linux won't make
use of it
- `linux-imx <https://github.com/nxp-imx/linux-imx>`_ (A55) needs the
NuttX compatible rpmsg_tty and rpmsg_fs drivers. See `dev mailing list
<https://www.mail-archive.com/dev@nuttx.apache.org/msg12112.html>`_

* Input Parameters:
* arg - The boardctl() argument is passed to the board_app_initialize()
* implementation without modification. The argument has no
* meaning to NuttX; the meaning of the argument is a contract
* between the board-specific initialization logic and the
* matching application logic. The value could be such things as a
* mode enumeration value, a set of DIP switch switch settings, a
* pointer to configuration data read from a file or serial FLASH,
* or whatever you would like to do with it. Every implementation
* should accept zero/NULL as a default configuration.
*
* Returned Value:
* Zero (OK) is returned on success; a negated errno value is returned on
* any failure to indicate the nature of the failure.
