[PATCH 5/8] drm: vmwgfx: Remove unneeded CRTC .prepare() helper operation

[Laurent Pinchart]

The CRTC .prepare() helper operation is part of the legacy helpers and
is deprecated in favour of the .disable() helper operation. As the
vmwgfx driver provides a .disable() helper operation, and as the
.prepare() helper operation implementation is empty, we can remove it.
