pinctrl: ingenic: Properly detect GPIO direction when configured for IRQ
The PAT1 register contains information about the IRQ type (edge/level)
for input GPIOs with IRQ enabled, and the direction for non-IRQ GPIOs.
So it makes sense to read it only if the GPIO has no interrupt
configured, otherwise input GPIOs configured for level IRQs are
misdetected as output GPIOs.
Fixes: ebd6651418b6 ("pinctrl: ingenic: Implement .get_direction for GPIO chips")
