Fix a problem observed while using fb_defio with a short delay on a
PowerPC platform.
It is possible that page_mkclean() is invoked in the deferred io work
function _before_ a PTE has been marked dirty. In this case, the page is
removed from the defio pagelist but page_mkclean() does not write-protect
the page again. The end result is that defio ignores all subsequent
writes to the page and the corresponding portions of the framebuffer never
get updated.
The fix consists in keeping track of the pages with non-dirty PTEs,
re-checking them again on the next deferred io work iteration. Note that
those pages are not passed to the defio callback as they are not written
by userspace yet.

This work includes the following:
- Implement handler for FBIO_WAITFORVSYNC ioctl.
- Allocate the data and palette buffers separately. A consequence of
this is that the palette and data loading is now done in different
phases. And that the LCD must be disabled temporarily after the palette
is loaded but this will only happen once after init and each time the
palette is changed. I think this is OK.
- Allocate two (ping and pong) framebuffers from memory.
- Add pan_display handler which toggles the LCDC DMA registers between
the ping and pong buffers.

of_platform_driver and converts all users to the device_driver members.
This patch is a pretty mechanical change. The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial. This patch looks big and scary because it touches so

Currently vesafb/efifb/... is kicked when hardware driver is registering
framebuffer. To do it hardware must be fully functional, so there's a short
window between start of initialisation and framebuffer registration when
two drivers touch the hardware. Unfortunately sometimes it breaks nouveau
initialisation.
Fix it by kicking firmware driver(s) before we start touching the hardware.
