Convert the regulator bindings to yaml.
Drop one twl5030 compatible due to no documentation on mfd side and no
users of the twl5030.

Changes in v4:
- remove a sentence in the commit message which only applies
to v1 design
- add R-by
Changes in v3:
- define regulator stuff in toplevel
- simplified regulator-inital-mode
- extended example to contain both regulator-initial-mode and
retain-on-reset
Changes in v2:
- add regulators directly to ti,twl.yaml
- less restrictions on regulator node name
