omapfb: dss: Fix max fclk divider for omap36xx

There appears to be a timing issue where using a divider of 32 breaks
the DSS for OMAP36xx despite the TRM stating 32 is a valid
number.  Through experimentation, it appears that 31 works.

This same fix was issued for kernels 4.5+.  However, between
kernels 4.4 and 4.5, the directory structure was changed when the
dss directory was moved inside the omapfb directory. That broke the
patch on kernels older than 4.5, because it didn't permit the patch
to apply cleanly for 4.4 and older.

A similar patch was applied to the 3.16 kernel already, but not to 4.4.
Commit 4b911101a5cd ("drm/omap: fix max fclk divider for omap36xx") is
on the 3.16 stable branch with notes from Ben about the path change.

Since this was applied for 3.16 already, this patch is for kernels
3.17 through 4.4 only.
