OMAPDSS: add FEAT_DPI_USES_VDDS_DSI to omap3630_dss_feat_list

commit 195e672a
   OMAPDSS: DPI: Remove cpu_is_xxxx checks

made the mistake of assuming that cpu_is_omap34xx() is exclusive of
other cpu_is_* predicates whereas it includes cpu_is_omap3630().

So on an omap3630, code that was previously enabled by
  if (cpu_is_omap34xx())
is now disabled as
  dss_has_feature(FEAT_DPI_USES_VDDS_DSI)
fails.

So add FEAT_DPI_USES_VDDS_DSI to omap3630_dss_feat_list.
