[PATCH driver-core-next] platform: remove useless if-branch in __platform_get_irq_byname()

[Soha Jin]

When CONFIG_OF_IRQ is not enabled, there will be a stub method that always
returns 0 when getting IRQ. Thus, the if-branch can be removed safely.

Fixes: d4ad017d6345 ("platform: use fwnode_irq_get_byname instead of of_irq_get_byname to get irq")
