Commit 845c8770 ("i2c / ACPI: Assign IRQ for devices that have
GpioInt automatically") automatically assigns the first ACPI GPIO
interrupt in client->irq, so we can remove the probing code from
drivers that use only one interrupt.

Commit 0f079650 ("iio: remove gpio interrupt probing from drivers
that use a single interrupt") removes gpio interrupt probing from most
drivers. This patch cleans the remaining ones.
