boards/stm32l4: Fix all boards to support proper stm32_bringup.c

[acassis]

Summary

Many STM32L4 boards are missing stm32_bringup.c. That confusion
was created when stm32_appinit.c was created. It introduced a new
way to do the board initialization without depending on NSH arch
specific initialization.

Impact

Fix boards bringup process.

Testing

Building

No, this PR does not fully meet the NuttX requirements. While it provides a summary of the what and why, it lacks crucial details.

Here's a breakdown of what's missing:

• Summary:
  • How does the change exactly work? It mentions removing the dependency on NSH arch initialization, but doesn't explain how it achieves that. Does it involve adding stm32_bringup.c files? Modifying existing files? What specific changes are made within those files?
• Impact: The impact section is far too brief. While it mentions fixing the bringup process, it needs to explicitly address all the points in the template. For example:
  • Impact on user: Even if the answer is NO, it should be stated explicitly.
  • Impact on build: While it mentions "Building," this isn't descriptive. Does the build process change in any way due to the addition/modification of files?
  • Impact on hardware: Which specific STM32L4 boards are affected?
  • Impact on documentation: Does this change necessitate documentation updates?
  • Impact on security, compatibility, etc.: All of these need to be addressed, even if the answer is NO.
• Testing:
  • Build Host(s): Missing operating system, CPU architecture, and compiler information.
  • Target(s): Missing specific architectures and board configurations tested.
  • Testing logs: Completely empty. Needs to include logs demonstrating the issue before the change and the improved behavior after the change. "Building" is not a testing log. Show output demonstrating successful bringup.

In short, the PR needs to be significantly more detailed to meet the requirements. It needs to clearly explain the technical implementation of the change, thoroughly address all aspects of its impact, and provide concrete evidence of testing on specific platforms.

Thank you @acassis !! I played a bit some time ago with STM32 boards and noticed the inconsistencies, thank you for the cleanup!! I have some of these boards, will test on hardware and report back :-)
