iio: proximity: sx9500: Assign interrupt from GpioIo()

Browse Source 
[ Upstream commit e53111ad5d ]

The commit 0f0796509c

("iio: remove gpio interrupt probing from drivers that use a single interrupt")

removed custom IRQ assignment for the drivers which are enumerated via
ACPI or OF. Unfortunately, some ACPI tables have IRQ line defined as
GpioIo() resource and thus automatic IRQ allocation will fail.

Partially revert the commit 0f0796509c to restore original behaviour.
