imx: imx9: Add TRDC driver for TRDC init
Add TRDC driver to iMX9. The TRDC init splits to two phases:
1. Early init phase will release TRDC from Sentinel and open write
permission to the memory where SPL image runs. Sentinel will set
the memory to RX only after ROM authentication for the OEM
closed part.
2. Init phase will configure TRDC to allow non-secure master to
access DDR. So the peripherals can work in u-boot.
