This adds the initial board configurattions for building NuttX for imxrt1189-evk.
Also add a script building the NXP container image for bootloaders (m33 images)
The board boots on Cortex-M33 core, for which there are two m33 targets: nsh-m33 and bl.
- "bl" target does basic initialization of ELE and TRDC and just releases the M7 to run
at 0x20080000.
- "nsh-m33" target just boots nuttx into nsh shell on m33
- The "nsh" target is for M7 core. It can be flashed at 0x20080000, and
it boots to nsh shell with a proper bootloader on m33 (the bl target does this).
