[PATCH] regulator: tps65917/palmas: Simplify multiple dereference of pdata->reg_init[idx]

[Nishanth Menon]

Converting dt to platform data logic involves picking up information
that is unique per regulator, however we can improve readability of
the code by allocating and referencing pdata->reg_init[idx] once in
the loop.

While at it, use sizeof(*pointer) when allocating pointer. This allows
for structure name changes with minimal code change.
