pinctrl: amd: Add IRQF_ONESHOT to the interrupt request
On some systems the interrupt is shared between GPIO controller
and ACPI SCI. When the interrupt is shared with the ACPI SCI the
flags need to be identical.
This should fix the GPIO controller failing to work after commit
7a36b901a6eb ("ACPI: OSL: Use a threaded interrupt handler for SCI").
```
[ 0.417335] genirq: Flags mismatch irq 9. 00000088 (pinctrl_amd) vs. 00002080 (acpi)
[ 0.420073] amd_gpio: probe of AMDI0030:00 failed with error -16
