Subject: [U-Boot][PATCH 1/1] lcd: align fb writing address for horizontal
display offset
CONFIG_SPLASH_SCREEN_ALIGN makes uboot support display offset for splashimage.
The framebuffer writing address should be calculated according to different
kinds of framebuffer pixel format, i.e., bits per pixel value.
