Originally based off of a patch by Kristian. This new ioctl extends DRM_IOCTL_MODE_GETPLANE, by returning information about the modifiers that will work with each format. It's modified from Kristian's patch in that the modifiers and formats are setup by the driver, and then a callback is used to create the format list. The LOC was enough difference that I don't think it made sense to leave his authorship, but the new UABI was primarily his idea. Additionally, I hit a couple of drivers which Kristian missed updating. It also contains a change requested by Daniel to make the modifiers array a sentinel based structure instead of a sized one. Upon discussion on IRC, it was determined that having an invalid modifier might make sense in general as well.
