Allow for a warm reset GPIO to be passed to the PMC driver via DT
which will be used to reset the system instead of writing to PMC_CTRL.
The GPIO will be asserted at reset time and, if this fails to reset
the system, we'll fall back to using PMC_CTRL.

There's actually gpio-restart driver now, which I think is what you
want instead of this.  See drivers/power/reset/gpio-restart.c.
