Please write normal conditional statements to make things easier to
read. It also looks like this would be more robustly written by just
having separate ops for DCDCs and LDOs, this could easily break if
another device is supported in the driver.

We don't need compatibles here, this is just reflecting the current
Linux device model into the OS neutral DT bindings. Another OS may
choose to split regulators up differently. We should just instantiate
the regulator device from the MFD based on identifying the chip overall.
