Subject: [PATCH] of_pci_irq: Silence bogus "of_irq_parse_pci() failed ..."
 messages.

It is perfectly legitimate for a PCI device to have an
PCI_INTERRUPT_PIN value of zero.  This happens if the device doesn't
use interrupts, or on PCIe devices, where only MSI/MSI-X are
supported.

Silence the annoying "of_irq_parse_pci() failed with rc=-19" error
messages by moving the printing code into of_irq_parse_pci(), and only
emitting the message for cases where PCI_INTERRUPT_PIN == 0 is not the
cause for an early exit.
