Thomas Petazzoni 397d59f3b5 arm: mvebu: add DT information for GPIO banks on Armada 370 and XP
The gpioX aliases are needed so that the driver can use
of_alias_get_id() to get a 0-based number of the GPIO bank, which we
then use to compute the base GPIO of the bank being probed. This is
similar to what gpio-mxs.c is doing.
