[PATCH 2/4] video: Assume video to be active if SPL is passing video hand-off

If SPL is passing video handoff structure to U-boot then it is safe to
assume that SPL has already enabled video and that's why it is passing
video handoff structure to U-boot so that U-boot can preserve the
framebuffer.
