Following are the changes since the previous version(v4):

 a. An if loop check while returning from lcd_disable_raster()
    function has been removed.
 b. "invert_pxl_clock" variable has been renamed as "invert_pxl_clk"
    and moved from lcd_ctrl_config structure in include/video/da8xx-fb.h
    file to da8xx_panel structure in drivers/video/da8xx-fb.c file.
    Appropriate changes in source code as a result of moving this
    variable has also been done.
