Add a binding to configure the internal charge pump for lp55xx.
Signed-off-by: Maarten Zanders <maarten.zanders@xxxxxxx>
---
Notes:
v1: implement as bool to disable charge pump
v2: rewrite to use string configuration, supporting all modes
v3: simplification by replacing string option by u8 constant,
removing previous Reviewed-by tags as it's a complete
rewrite of the patch.
v4: added notes
