usb: host: ohci-at91: fix request of irq for optional gpio
atmel,oc-gpio is optional. Request its irq only when atmel,oc is set
in device tree.
devm_gpiod_get_index_optional returns NULL if -ENOENT. Check its
return value for NULL before error, because it is more probable that
atmel,oc is not set.
This fixes the following errors on boards where atmel,oc is not set in
device tree:
[ 0.960000] at91_ohci 500000.ohci: failed to request gpio "overcurrent" IRQ
[ 0.960000] at91_ohci 500000.ohci: failed to request gpio "overcurrent" IRQ
[ 0.970000] at91_ohci 500000.ohci: failed to request gpio "overcurrent" IRQ
