drm/i915: Disable planes more atomically during modesets

Browse Source 
Follow in the footsteps of commit c610e841f1 ("drm/i915:
Do plane/etc. updates more atomically across pipes") and
do the plane disables back to back for all pipes also when
we are disabling pipes.

This should provide for a potentially more atomic user
experience, which might be especially nice when using
joiner or tiled displays.
