There already was an option for autoconfiguring IPv4 from QMI but this
was removed by commit 3b9b963e6e ("uqmi: always use DHCP for IPv4").
DHCP does not work on MR400 LTE module (in TL-MR6400 v4) so let's readd
support for IPv4 autoconf from QMI but this time allow to configure this
for IPv4 and IPv6 independently and keep DHCP default on IPv4.

Give possibility to wait forever the registration by setting timeout
option to 0.
No timeout can be useful if the interface starts whereas no network is
available, because at the end of timeout the interface will be stopped
and never restarted.
