URL: https://github.com/apache/nuttx/pull/20695
## Summary
Add support to Digital Dream EC300 board. This board is powered by iMXRT1052
and it was developed to work with Mach3.
However some years ago the Remona firmware added support to work with
LinuxCNC.
## Impact
Users could use this board with NuttX.
