pinctrl: sunxi: fix gpiochip_lock_as_irq() failure when pinmux is unknown
Fixes kernel hang during boot due to inability to set up IRQ on AXP313a.
The issue is caused by gpiochip_lock_as_irq() which is failing when gpio
is in uninitialized state.
Solution is to set pinmux to GPIO INPUT in
sunxi_pinctrl_irq_request_resources() if it wasn't initialized
earlier.
Tested on Orange Pi Zero 3.
