a8753afed7 imx: imx9: Add M33 release prepare function
To support on-demand booting M33 image from A core. SPL needs
to follow M33 kick up sequence to release M33 firstly,
then set M33 CPUWAIT signal. ATF will clear CPUWAIT to kick
M33 to run.

The prepare function also works around the M33 TCM ECC issue by
clean the TCM. Also enable sentinel handshake and WDOG1 clock
for M33 stop and reset.

5fda95fb94 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.

636c95f82b imx: imx9: support romapi
i.MX9 shares same ROM API with i.MX8ULP, so make the i.MX8ULP the function
prototype common and usable by i.MX9.

Also include mmc env functions that use ROM API.
