pinctrl: st: add irq_request/release_resources callbacks
When using GPIO as IRQ source, the GPIO must be configured in INPUT. Callbacks dedicated for this was missing in pinctrl-st driver. This fix the following kernel error when trying to lock a gpio as IRQ: [ 7.521095] gpio gpiochip7: (PIO11): gpiochip_lock_as_irq: tried to flag a GPIO set as output for IRQ [ 7.526018] gpio gpiochip7: (PIO11): unable to lock HW IRQ 6 for IRQ [ 7.529405] genirq: Failed to request resources for 0-0053 (irq 81) on irqchip GPIO Signed-off-by:Patrice Chotard <patrice.chotard@st.com> Signed-off-by:
