Update bindings for the Dialog Semiconductor DA9121 voltage regulator to add device variants. Because several variants have multiple regulators, and to regard potential to add GPIO support in future, the 'regulators' sub-node is added, following the precedent set by other multi-regulator devices, including the DA9211 family. This breaks compatibility with the original submission by Vincent Whitchurch - but as this is still in for-next, the alignment could be made before upstreaming occurs.
