iris: Actually advertise some modifiers

I neglected to fill out this driver function, causing us to advertise
0 modifiers.  Now we advertise the various tilings and let the driver
pick them.  I've verified that X tiling works with Weston (by hacking
the list to skip Y tiling).

Y+CCS doesn't work yet because it's multiplane and the Gallium dri
state tracker isn't really prepared for that.  Leave it off for now.
