The regulator_desc arrays in this driver are indexed by RN5T618_* constants and some elements can be missing. This causes probe failures on older models:
rn5t618-regulator rn5t618-regulator: failed to register (null) regulator rn5t618-regulator: probe of rn5t618-regulator failed with error -22 Fix this by making the arrays flat. This also saves a little memory because the regulator_desc arrays become smaller.
