Commit c2e13037e6794bd0d9de3f9ecabf5615f15c160b ("platform-drivers: move
probe to .devinit.text in drivers/video") introduced a huge amount of
section mismatch warnings in vesafb code.  Rather than converting all of
the annotations, do the obvious and revert the __init -> __devinit change,
and use the recommended (in that patch) alternative to calling
platform_driver_register(): vesafb depends on information obtained from by
kernel at boot time, cannot be a module, and no post-boot devices can ever
show up.
