Add necessary Kconfigs to enable video driver and enable splash screen
at spl stage.
CONFIG_SPL_VIDEO enables all necessary configs enabled by CONFIG_VIDEO
at spl stage.
CONFIG_SPL_SYS_WHITE_ON_BLACK allows displaying on black background at
spl stage.
These configs are specific to SPL and will allow us to enable the video
driver and splash screen at SPL stage only and not at u-boot proper.
The existing Kconfigs from u-boot proper were not used to make SPL
splash screen independent to them.
Enable BMP_GZIP at SPL stage when SPL_SPLASH_SCREEN or SPL_CMD_BMP are
defined.
