gpio: dwapb: Drop redundant check in dwapb_irq_set_type()

Browse Source 
For more than 15 years we may not get into ->irq_set_type()
without any meaningful type provided.

Drop redundant check in dwapb_irq_set_type().

See the commit e76de9f8eb ("[PATCH] genirq: add SA_TRIGGER support")
out of curiosity.
