[PATCH] pinctrl/at91: Don't provide a default trigger type

[Marc Zyngier]

at91 used to set a default trigger type for GPIO interrupts in
order to cope with the old board files. These days are long gone,
and it all gets probed through DT.

Andras Szemzo reported that the Ethernet device on his board was
bailing to be probed, due to a conflict in interrupt trigger.
Surely enough, this is due to this default trigger still being
present, and turning this into a IRQ_TYPE_NONE fixes the issue.
