Isn't that always defined? Probably don't need this #ifdef. Also can
you add a TODO to drop this table in favour of device tree?

Should define a struct for this peripheral.

What are 11 and 27? Should they have an enum?

Repeating code here and below - how about a function to enable a given clock?

This should go in a PMIC driver. Ideally most of this would happen
automatically if the voltages are in the device tree, but since you
don't have one, I suggest just moving this code into the driver.
