drm: Nuke modifier[1-3]

It has been suggested that having per-plane modifiers is making life
more difficult for userspace, so let's just retire modifier[1-3] and
use modifier[0] to apply to the entire framebuffer.

Obviosuly this means that if individual planes need different tiling
layouts and whatnot we will need a new modifier for each combination
of planes with different tiling layouts.

For a bit of extra backwards compatilbilty the kernel will allow
non-zero modifier[1+] but it require that they will match modifier[0].
This in case there's existing userspace out there that sets
modifier[1+] to something non-zero with planar formats.

Mostly a cocci job, with a bit of manual stuff mixed in.
