Only pulling out the _common_ stuff. This is a single step in a long process of eliminating all the duplication and "same, but different" implementations that are stalling adding nice clean easy support for l0/f7/l4. This _ignores_ all currently conflict register definitions, even if they "do the same thing" it just pulls up the common stuff. A subsequent commit can look at resolving the implementatations to a single version.
