iommu: Use dev_printk() when possible
Use dev_printk() when possible so the IOMMU messages are more consistent
with other messages related to the device.
E.g., I think these messages related to surprise hotplug:
pciehp 0000:80:10.0:pcie004: Slot(36): Link Down
iommu: Removing device 0000:87:00.0 from group 12
pciehp 0000:80:10.0:pcie004: Slot(36): Card present
pcieport 0000:80:10.0: Data Link Layer Link Active not set in 1000 msec
would be easier to read as these (also requires some PCI changes not
included here):
pci 0000:80:10.0: Slot(36): Link Down
pci 0000:87:00.0: Removing from iommu group 12
pci 0000:80:10.0: Slot(36): Card present
pci 0000:80:10.0: Data Link Layer Link Active not set in 1000 msec
