A local variable hiding the one with the same name at an upper scope,
resulted in storing the register address instead of the desired value in
LCD registers.

In register writes there is no extra cycle after the command, so we use
only 9-bit word size.

- Support for the Philips LPH8923 LCD panel
- Support for the Epson HWA742 LCD controller

- Support for frame buffer located in SRAM and/or SDRAM
- Support for boot loader initialized LCD controller / frame buffer
  content.

- LCD panels will now register a device in the relevant board-* files
  instead of specifying the LCD type as an OMAP_TAG_LCD. The controller
  type is still specified in OMAP_TAG_LCD.
- A new ATAG OMAP_TAG_FBMEM is used to describe the frame buffer memory
  configuration (SRAM and SDRAM regions)

- Changed the OMAP1 LCD controller driver to export its functions
  through the lcd_ctrl object.
- OMAP1 pixel clock divider will now round up in lcdc.c
- Changed the OMAP1 SoSSI driver to export its functions through the
  lcd_ctrl_extif object.
- OMAP1 SoSSI clock calculation goes through all possible clock
  dividers. Rounding of clock tick values now takes places at each
  timing parameter.

- OMAP2 RFBI clock calculation goes through all possible clock
  dividers. Rounding of clock tick values now takes places at each
  timing parameter.
- OMAP2 pixel clock divider will now round up in dispc.c
