gpio: mlxbf3: use platform_get_irq_optional()

JIRA: https://issues.redhat.com/browse/RHEL-103570

This merge request updates the BlueField-3 GPIO driver to prevent the error message "IRQ index 0 not found" from appearing in kernel log. The driver has been updated to use "platform_get_irq_optional()" to suppress any error logging. The testing is simple, and just involves loading the driver, executing 'dmesg', and checking for any errors.
