that are available for radeon's use with KV.
This patch reserves VMIDs 8-15 for amdkfd (so radeon can only use VMIDs
0-7) and also makes radeon thinks that KV has only a single MEC with a single
pipe in it

This patch creates a workaround for a bug in amd_iommu driver, where the driver
doesn't save all necessary information when going to suspend.
The workaround removes a device from the IOMMU device list on suspend and
register a resumed device in the IOMMU device list.
