of_mdio: move of_mdio_parse_addr to header file
The of_mdio_parse_addr() helper function is useful to other code, but
the module dependency chain causes issues. To work around this, we can
move of_mdio_parse_addr() to be an inline function in the header file.
This gets rid of the dependencies and still allows for the reuse of
code.
