The "vdd" and "vddio" regulators are always controlled together. Switch
to the regulator bulk API to handle setup, enable, and disable paths in
a single call.
No functional change intended.

Introduce a local struct device pointer derived from &client->dev.
This avoids repeated &client->dev usage and improves readability.

Applied to the testing branch of iio.git. Note that branch will be
rebased on rc1 once available in about 3 weeks time (and maybe
I'll rebase on intermediate baselines in between).
