Revert "drm/mgag200: Add vblank support"
This reverts commit 6c9e14ee9f519ee605a3694fbfa4711284781d22.
This reverts commit d5070c9b29440c270b534bbacd636b8fa558e82b.
This reverts commit 89c6ea2006e2d39b125848fb0195c08fa0b354be.
The VLINE interrupt doesn't work correctly on G200SE-A (at least). We
have also seen missing interrupts on G200ER. So revert vblank support.
Fixes frozen displays and warnings about missed vblanks.
[ 33.818362] [CRTC:34:crtc-0] vblank wait timed out
From the vblank code, the driver only keeps the register constants and
the line that disables all interrupts in mgag200_device_init(). Both
is still useful without vblank handling.
