doc: improve the doxygen description of default_val(s)

Users report being confused by the name 'default_val(s)' for function
parameters. Because it's in line with the kernel uAPI, we'll leave it
like this, but let's improve the documentation a bit by stating
explicitly that this parameter represents the initial values for
requested GPIO lines.
