[PATCH] platform: use fwnode_irq_get_byname instead of of_irq_get_byname to get irq

[Soha Jin]

Not only platform devices described by OF have named interrupts, but
devices described by ACPI also have named interrupts. The fwnode is an
abstraction to different standards, and using fwnode_irq_get_byname can
support more devices.
