efi: Support a 64-bit frame buffer address
The current vesa structure only provides a 32-bit value for the frame
buffer. Many modern machines use an address outside the range.
It is still useful to have this common struct, but add a separate
frame-buffer address as well.
Add a comment for vesa_setup_video_priv() while we are here.
