91e976777d drm/amd|radeon: Drop drm_vblank_cleanup 
Both drivers shut down all crtc beforehand already, which will shut up
any pending vblank (the only thing vblank_cleanup really does is
disable the disable timer). Hence we don't need this here and can
remove it.

Newer asics have a two levels of irq ids now:
client id - the IP
src id - the interrupt src within the IP

v2: integrated Christian's comments.

    drm: Rework vblank-wait handling to allow interrupt reduction.

to stay backwards-compatible with old UMS code that didn't even tell
the kernel when it did a modeset, so that the kernel could
save/restore vblank counters. At worst this means vblanks will be
somewhat funky on a setup that very likely no one still runs.

So let's just nuke it.

Plan B would be to set it unconditionally in drm_vblank_init for kms
drivers, instead of in each driver separately. So if this patch breaks
anything please only restore the hunks in drmP.h and drm_irq.c, plus
add a check for DRIVER_MODESET in drm_vblank_init.

Stumbled over this in a discussion on irc with Chris.

This patch marks some compile-time constant tables 'const'.
The tables marked in this patch are the low hanging fruit
where little other changes were necesary to avoid casting
away constness etc. Also mark some tables that are private
to a file as static.
