ENGR00137894-6 MX53 SMD:Support splashimage
This patch supports to use pwm wave to control
backlight. The pwm rate is 20KHz and the pwm
duty is 50%. Only lvds panel is supported.
Use 'lvds_num' env variable to choose to use
lvds0 or lvds1. However, only lvds1 is tested
as the lvds cable cannot be plugged into lvds0
connector. Note that you need to add 'splashimage'
env variable to set the memory address of the
bmp image.
