drivers/video:     fb driver now clears framebuffer initially.  Eliminates (or minimizes) initial garbage on the display.
    configs/open1788:  Initialization now follows the pattern of other boards.  Add initialization of fb driver.
    configs/open1788:  Add a configuration for testing the framebuffer driver.
