The reason is already explained here:

Commit 5033ad566016 fixed the issue, but the MIPS maintainer
simultaneously applied commit 101bd58fde10, which introduced
another instance of the same mistake.

I will not ask him to pick up this any more.
That would take two development cycles until this choice structure
is banned. Meantime, MIPS would introduce yet another mistake.

I will apply both to my tree.

The second patch makes it an error to stop this whack-a-mole game.

  MIPS: move unselectable FIT_IMAGE_FDT_EPM5 out of the "System type"
    choice
  kconfig: do not reparent the menu inside a choice block
