U-boot proper can use frame buffer address passed from SPL to reserve
the memory area used by framebuffer set in SPL so that splash image
set in SPL continues to get displayed while u-boot proper is running.

Put the framebuffer address and size in a bloblist to make them
available at u-boot proper, if in u-boot proper CONFIG_VIDEO is defined.
