arch: i.MX add RDC peripheral permission setting for applications cores 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. Signed-off-by: Diego Sueiro <diego.sueiro@gmail.com>
