[PATCH v2 0/9] video: screen_info cleanups

From: Arnd Bergmann <arnd@arndb.de>

I refreshed the first four patches that I sent before with very minor
updates, and then added some more to further disaggregate the use
of screen_info:

 - I found that powerpc wasn't using vga16fb any more

 - vgacon can be almost entirely separated from the global
   screen_info, except on x86

 - similarly, the EFI framebuffer initialization can be
   kept separate, except on x86.

I did extensive build testing on arm/arm64/x86 and the normal built bot
testing for the other architectures.

Which tree should this get merged through?
