Because it was effectively a dead code (disabled by a DT flag property)
and didn't make any sense on our test board. It was setting regulator's
load and voltage on a shared fixed voltage regulator. Even if calls like
regulator_set_optimum_mode() were added that wouldn't make any difference,
since the corresponding PMIC driver ops were not implemented.
I started more or less with something like this [1].

Will do in next iteration. Thanks for your review.
