Replace irq_of_parse_and_map() with platform_get_irq() as recommended
for device-managed IRQ lookup. Properly propagate any errors returned
from platform_get_irq(). irq_of_parse_and_map() requires
ire_dispose_mapping(), which is missing.
irq_of_parse_and_map() and platform_get_irq() look pretty different, can
you give more details on how one can replace the other ? (I don't mean
this is wrong, just I don't have enough details).
