- Pass the correct IRQ domain to generic_handle_domain_irq() to fix a
  regression when converting to msi_create_parent_irq_domain() (Claudiu
  Beznea)

- Drop the spinlock protecting the PMSR register; it's no longer required
  since pci_lock already serializes accesses (Marek Vasut)

- Convert struct rcar_msi mask_lock to raw spinlock to avoid a lock nesting
  error (Marek Vasut)
