gpio: mlxbf3: use platform_get_irq_optional()
commit 810bd9066fb1871b8a9528f31f2fdbf2a8b73bf2 upstream.
The gpio-mlxbf3 driver interfaces with two GPIO controllers,
device instance 0 and 1. There is a single IRQ resource shared
between the two controllers, and it is found in the ACPI table for
device instance 0. The driver should not use platform_get_irq(),
otherwise this error is logged when probing instance 1:
mlxbf3_gpio MLNXBF33:01: error -ENXIO: IRQ index 0 not found
