A perfect driver would only call dev_iommu_priv_set() from its probe callback. We've made it functionally correct to call it from the of_xlate by adding a lock around that call. lockdep assert that iommu_probe_device_lock is held to discourage misuse. Exclude PPC kernels with CONFIG_FSL_PAMU turned on because FSL_PAMU uses a global static for its priv and abuses priv for its domain. Remove the pointless stores of NULL, all these are on paths where the core code will free dev->iommu after the op returns.
