xf86-video-ati: (revised #2) add support for vblank on crtc > 1

Hi Alex,

Enclosed is a revised version of two patches sent on Mar 18 and Mar 22,
respectively. Details summarized in these two threads:
http://lists.freedesktop.org/archives/dri-devel/2011-March/009463.html
http://lists.freedesktop.org/archives/dri-devel/2011-March/009582.html

This patch reconciles the DDX with the change in libdrm sent to this list
earlier today. Specifically, it refers to a symbol that has been renamed
from DRM_CAP_HIGH_CRTC to DRM_CAP_VBLANK_HIGH_CRTC. It *supersedes* the
previous patch (i.e. apply it to the master branch as it exists at the
time of this writing, not as an incremental patch to the one sent previously).

Regards,

Ilija
