[PATCH] modesetting: call xf86HandleColormaps

[Rinat Ibragimov]

Long ago, it was possible to apply color profile with modesetting driver.
But it's not working now. (Stopped approximately after 1.19.0 release).
Bisecting points to the patch b4e46c04 (xfree86: Hook up colormaps and
RandR 1.2 gamma code v6). Applying color profile still works with intel
driver.

As far as I understand, it was working because there were fall-backs which
were removed by the patch b4e46c04. And now, since modesetting does not
provide LoadPalette method, fails. Fortunately, there is
drmmode_setup_colormap(), which in turn calls xf86HandleColormaps().

Patch below works on my machine. "xcalib -i -a" inverts colors as before.
Applying .icc file also changes colors as expected. But this colormap
handling surely has pitfalls. So I'm not sure. Is this a correct way to fix it?
