of/irq: do irq resolution in platform_get_irq_byname()
The commit 9ec36cafe43bf835f8f29273597a5b0cbc8267ef "of/irq: do irq resolution in platform_get_irq" from Rob Herring - moves resolving of the interrupt resources in platform_get_irq(). But this solution isn't complete because platform_get_irq_byname() need to be modified the same way. Hence, fix it by adding interrupt resolution code at the platform_get_irq_byname() function too.
