This patch adds a new function to update color blob properties and exports it.

v2: Addressing Sonika's comment,

1. Moved this function to a separate patch
2. Removed one input parameter to the function

This function is basically just a pass-through. Can we just un-static drm_property_replace_global_blob() so that it can be called directly instead?

Matt

Yes, sure. In fact we would like to do that, the same comment was given by other reviewers. But when we looked at some other examples present in the same file (mode_property, edid_property), they have created a wrapper function around this, in the same file. So just followed the convention, but if that can be done, we will do it in the next patch set.

I think those other functions started out as somewhat more complicated functions before drm_property_replace_global_blob() ever existed, then eventually got whittled down to their current state via refactoring. Rather than creating new functions today it's probably easiest to just unstatic the function here so it can be called directly.
