ENGR00179000 i.mx6q/dl: sabresd: Add the splash screen support

This patch will add the splash screen support for the
i.mx6q/dl splash screen support.

In order to enable the splash screen, you need make sure
the following env variable has been set correctly:

splashimage=0x30000000
splashpos=m,m
lvds_num=0

The splash screen is default OFF, to enable it, please add:
on i.mx6dq sabresd platform:
define CONFIG_SPLASH_SCREEN in include/configs/mx6q_sabresd.h
or on i.mx6dl sabresd platform:
define CONFIG_SPLASH_SCREEN in include/configs/mx6dl_sabresd.h
