anv: Delete stale comment for BLORP clear color addr

It looks like this comment attempted to describe all the reasons we need
to pass the clear color address to BLORP. This comment actually isn't
exhaustive and some bits are out of date (e.g., BLORP no longer updates
the clear color address for us). Let's just delete it.
