gpio: mlxbf2: use platform_get_irq_optional()
The gpio-mlxbf2 driver interfaces with four GPIO controllers,
device instances 0-3. There are two IRQ resources shared between
the four controllers, and they are found in the ACPI table for
instances 0 and 3. The driver should not use platform_get_irq(),
otherwise this error is logged when probing instances 1 and 2:
mlxbf2_gpio MLNXBF22:01: error -ENXIO: IRQ index 0 not found
