- fix imx93 m33 user space issue
- test pass in hello_world_user for imx93 cm33
This update ensures that TRDC settings are correctly applied when user space is enabled. By default, the M33 core operates in privileged mode. However, when user threads are scheduled, the system transitions to unprivileged mode. The TRDC configuration is adjusted to support this behavior, maintaining secure and functional access control for both privileged and unprivileged execution contexts.

Some SoCs such as iMX8ULP and iMX93 use sentinel controller for secure system management, this change ensures the device driver is available by default. Signed-off-by: Yongxu Wang <[email protected]>
