irqchip/mips-gic: Cleanup chip and handler setup
gic_shared_irq_domain_map() is called from gic_irq_domain_alloc() where the wrong chip has been set, and is then overwritten. Tidy this up by setting the correct chip the first time, and setting the handle_level_irq handler from gic_irq_domain_alloc() too. gic_shared_irq_domain_map() is also called from gic_irq_domain_map(), which now calls irq_set_chip_and_handler() to retain its previous behaviour. This patch prepares for a follow-on which will call gic_shared_irq_domain_map() from a callback where the lock on the struct irq_desc is held, which without this change would cause the call to irq_set_chip_and_handler() to lead to a deadlock.
