[PATCH] iommu/arm-smmu: Demote error messages to debug in shutdown callback

[Sai Prakash Ranjan]

Currently on reboot/shutdown, the following messages are
displayed on the console as error messages before the
system reboots/shutdown.

On SC7180:

  arm-smmu 15000000.iommu: removing device with active domains!
  arm-smmu 5040000.iommu: removing device with active domains!

Demote the log level to debug since it does not offer much
help in identifying/fixing any issue as the system is anyways
going down and reduce spamming the kernel log.
