Use devm here to save some lines and prepare for bulk regulator usage in
this driver. Otherwise, when we devm bulk get regulators we'll free the
containing i2c_hid structure and try to put regulator pointers from
freed memory.

The wacom w9013 device has two supplies that need to be turned
on and in some cases these come from two different power supplies.
This patch series supports that case.
Changes from v1:
* Use the bulk regulator APIs instead of open coding it (Dmitry)
Changes from v2:
* Split out devm for allocat
Some wacom w9013 devices have a vddl supply for "low valtage"
requirements. Add support in this driver to turn on this low voltage
supply. We can also drop a handful of error messages because the
regulator core is already printing an error when bulk regulators fail to
enable or disable.

Hi Federico,
Thanks for the analysis. I'll probably not be able to look into this
very much until next week. A few notes below.

Hi,
A few more things I noticed; probably my last thoughts on this
particular patch; and I think I reviewed the rest:
