  Provide the 1.8 and 3.3 volt regulators that are utilised on the Debix
SOM BMB-08 base board.

Facilitate this by also supplying the pin control used to enable the
regulators on the second MIPI CSI port.

Can we drop the _SW suffix here and below? I like to align the names
with the schematic power-rail names to make it easier to grep.

With that fixed feel free to add my:

Sure that's fine with me. I think the _SW is probably a hangover from
the BSP kernel, I'm not sure why I kept it ;-)
