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.
