[PATCH v3 2/2] drivers: iio: admv1013: add vcc regulators

[Antoniu Miclaus <antoniu.miclaus@analog.com>]

Add regulators for the VCC supplies of the admv1013.

The patch aims to align the implementation with the current admv1014
driver where all the VCC supplies are handled as regulators.

changes in v3:
 - add missing spaces in the commit subject.
 - use dev_err_probe for error handling.
 -  - use `devm_regulator_bulk_get_enable`
