Shouldn't this be the first commit in the series?  Also...

I can't help but think that if we're going to require the full array
here the array should just be declared immediately - perhaps as an array
of pointers:

	struct regulator_init_data *reg_init_data[TPS65090_REGULATOR_MAX];

to allow things to be missed out.  Otherwise we're likely to crash if
the user misses a regulator or something.
