Joerg Roedel 8704a1ba47 iommu/amd: Split amd_iommu_init function
The hardware-initializtion part of the AMD IOMMU driver is
split out into a seperate function. This function can now be
called either from amd_iommu_init() itself or any other
place if the hardware needs to be ready earlier. This will
be used to implement interrupt remapping for AMD.

Joerg Roedel bc21662f72 iommu/amd: Add invalidate-context call-back
This call-back is invoked when the task that is bound to a
pasid is about to exit. The driver can use it to shutdown
all context related to that context in a safe way.
