When testing SD hotplug automatically, I got bunch of
useless log like this:

Moreover the code is intent to print the 'uV' for debug but
later print it using dev_info. It looks more like to me that
it should be the real intention of the code. Anyway, let's
mark this verbose log as debug message.

reducing the amount of logs, especially for information not generally needed 
looks sane

Rafael, feel free to apply directly as a fix for v4.9-rc, or wait for
v4.10 if you prefer.
