Update sabre-6quad with QEMU

[masayuki2009]

Summary

• This commit consists following two commits
  • commit 1: boards: sabre-6quad: Enable DEBUG_ASSERTION in citest
    • Since QEMU does not report L2CC information correctly,
      NuttX stops if DEBUG_ASSERTIONS=y.
    • This commit adds DEBUG_ASSERTIONS=y to citest/defconfigs
      and disables L2CC related configs.
    • Also, it disables RAMLOG to show the crash information
  • commit 2: boards: sabre-6quad: Update README.txt

Impact

• None

Testing

• Tested with QEMU-7.1

Let me try if sabre-6quad:citest works with this PR.
#8364

Hmm, it seems that heap corruption happened.
However, I can not reproduce the crash locally.

I can reproduce the crash.

I will fix common.py in this PR.

It seems all the tests passed.
