ext/hal/nxp/imx: Import the nxp imx7 freertos bsp

This code component is used to add Zephyr support on iMX7 processors, exclusively on Cortex M4 core, and to speed up the development process it was decided to have it based on NXP FreeRTOS BSP implementation. The source code was imported from the following folders: FreeRTOS_BSP_1.0.1_iMX7D/platform/drivers FreeRTOS_BSP_1.0.1_iMX7D/platform/devices This source code depends on headers and sources from zephyr: ext/hal/cmsis Origin: iMX7D NXP FreeRTOS BSP Peripheral Driver License: BSD 3-Clause URL: https://www.nxp.com/webapp/Download?colCode=FreeRTOS_iMX7D_1.0.1_LINUX&appType=license commit: no commit hash Purpose: The peripheral driver wraps the H/W for i.MX7 M4 core Maintained-by: External Signed-off-by: Diego Sueiro <[email protected]>
