## Summary

* boards/xtensa/esp32: increase MM_REGIONS for psram defconfig
Increase MM_REGIONS from 5 to 6 to accomodate latest changes from
initialization refactor.
This change was necessary since the arch init changes on #18832. We fixed
some issues on ESP32-S3 but seems we forgot about this one.
## Impact
<!-- Please fill the following sections with YES/NO and provide a brief
explanation -->
Impact on user: Fix esp32-devkitc:psram boot when DEBUG_ASSERTIONS are
enabled.
<!-- Does it impact user's applications? How? -->
Impact on build: No.
<!-- Does it impact on building NuttX? How? (please describe the required
changes on the build system) -->
Impact on hardware: No.
<!-- Does it impact a specific hardware supported by NuttX? -->
Impact on documentation: No.
<!-- Does it impact the existing documentation? Please provide additional
documentation to reflect that -->
Impact on security: No.
<!-- Does it impact NuttX's security? -->
Impact on compatibility: No.
<!-- Does it impact compatibility between previous and current versions? Is
this a breaking change? -->
## Testing
<!-- Please provide all the testing procedure. Consider that upstream
reviewers should be able to reproduce the same testing performed internally -->
Build the psram defconfig before and after the change.
### Building
<!-- Provide how to build the test for each SoC being tested -->
- ./tools/configure.sh esp32-devkitc:psram
- Enable DEBUG_ASSERTIONS
- Build and flash
### Results
<!-- Provide tests' results and runtime logs -->
