As of the commit 1de452a0ed ("regulator: core: Allow drivers to
define their init data as const") we no longer need to do copying of
regulator bulk data from initdata to something dynamic. Let's take
advantage of that.
In addition to saving some code, this also moves us to using
ARRAY_SIZE() to specify how many regulators we have which is less
error prone.
This gets rid of some layers of wrappers which makes it obvious that
we can get rid of an extra error print.
devm_regulator_bulk_get_const() prints errors for you so you don't
need an extra layer of printing.
In all cases here I have preserved the old settings without any
investigation about whether the loads being set are sensible. In the
cases of some of the PHYs if several PHYs in the same file used
exactly the same settings I had them point to the same data structure.
NOTE: Though I haven't done the math, this is likely an overall
savings in terms of "static const" data. We previously always
allocated space for 8 supplies. Each of these supplies took up 36
bytes of data (32 for name, 4 for an int).
