Merge OMAP5 DSS changes to omapdss

This series adds basic OMAP5 DSS functionality, mainly related to DSS core, DPI
and DSI.

* omap5-dss:
  OMAPDSS: DSI: make OMAP2_DSS_DSI depend on ARCH_OMAP5
  OMAPDSS: DSI: Add code to disable PHY DCC
  OMAPDSS: DSI: Add new linebuffer size for OMAP5
  OMAPDSS: DSI: Add FEAT_DSI_PLL_REFSEL
  OMAPDSS: DSI: Add FEAT_DSI_PLL_SELFREQDCO
  OMAPDSS: Add support for DPI source selection
  OMAPDSS: move dss feats to the end of dss.c
  OMAPDSS: Add basic omap5 features to dss and dispc
  OMAPDSS: DSI: improve DSI clock calcs for DISPC
