Subject: serial-apbuartc-fix-two-problems-related-to-grlib_apbuart_configure-update.
From: Miguel Ojeda <miguel.ojeda.sandonis@gmail.com>

Changes:
1. Added the grlib_apbuart_port_nr = 0 line.
2. Returned -ENODEV instead of 0 in the "no ports found branch" in
init(), because if compiled as a module, exit() will try to unregister
things that were not registered. In addition, this will alert the users
that modprobe'd.
3. Deleted the unused __FILE__ argument of the previous patch (oops
sorry :).
