LCD config for old omapfb driver is passed with OMAP_TAG_LCD from board files or from the bootloader. In an effort to remove OMAP_TAG_LCD, this patch adds omapfb_set_lcd_config() function that the board files can call to set the LCD config. This has the drawback that configuration can no longer come from the bootloader. Of the boards supported by the kernel, this should only affect N770 which depends on the data from the bootloader. This patch adds an LCD config for N770 to its board files, but that is most probably broken. Fixing this would need information about the HW setup in N770 boards.
