Jerome Glisse d39c3b8958 drm/radeon/kms: Convert RV515 to new init path and associated cleanup
Convert the rv515 asic support to new init path also add an explanation
in radeon.h about the new init path. There is also few cleanups
associated with this change (others asic calling rv515 helper
functions).
