We currently get a warning for lcdc because of a difference

Hi Tony,
While I understand that you are trying to match the DT data with the
existing legacy data, do you know if there was a reason why this was
omitted in the first place? Should we be really adding the MSTANDBY_
flags and fix up the DTS node accordingly? I tried looking through the
git log, and the initial commit itself didn't add the MSTANDBY_ flags
but used the SYSC_HAS_MIDLEMODE.
Jyri,
Do you know the history?
Tony/Suman,
This patch breaks DS0 on am3.

Let's fix the warning by removing SYSC_HAS_MIDLEMODE. Note that
the am335x TRM lists SYSC_HAS_MIDLEMODE, but it is unused.
