Add support for ADP5055 triple buck regulator.
Merge series from Alexis Czezar Torreno <alexisczezar.torreno@analog.com>: Introduce a regulator driver support for ADP5055. The device combines 3 high performance buck regulators in a 43-termminal land grid array package. The device enables direct connection to high input voltages up to 18V with no preregulator. Channel 1 and 2 deliver a programmable output current of 3.5A or 7.5A or provide a single output with up to 14A in parallel operation. Channel 3 has a programmable output current of 1.5A or 3A.

the driver automatically switches to software only mode.
