regulator: da9121: Add DA914x binding info

Browse Source 
Add the configuration for the DA9141 and DA9142 regulators.
Also tidy the table, cleaning away superfluous information.

Current limits
Device parameter ranges
This is PER PHASE, and the current limit setting in the devices reflect
that with a maximum 10A limit. Allowing for transients at/near double
the rated current, this translates across the device range to per
channel figures as so...
The current limits can be set to at/near double the rated current per channel
to allow for transient peaks.
Current limit changes when the output is enabled are not supported, as a
precaution against undefined behaviour.
