[PATCH] m68k: mvme: Remove overdue #warnings in RTC handling

[Geert Uytterhoeven]

The warnings were introduced when converting the MVME147 and MVME16x
RTC handling from gettod to hwclk.  Replace the #warning by a comment,
and return an error to inform the upper layer that writing to the RTC is
not yet supported.
