of: of_parse_phandles_with_args() learns to differentiate 'hole' cells
Given this list (contains three gpio specifiers, one of which is a hole):
gpios = <&phandle1 1 2 3
0 /* a hole */
&phandle2 4 5 6>;
of_parse_phandles_with_args() would report -ENOENT for the `hole'
specifier item, the same error value is used to report the end of the
list, for example.
Sometimes we want to differentiate holes from real errors -- for
example when we want to count all the [syntax correct] specifiers.
With this patch of_parse_phandles_with_args() will report -EEXITS when
somebody requested to parse a hole.
Also, make the out_{node,args} arguments optional, when counting we
don't really need the out values.
