iommu/vt-d: Allow devices with RMRRs to use identity domain commit 9235cb13d7d17baba0b3a9277381258361e95c16 upstream. Since commit ea2447f700cab ("intel-iommu: Prevent devices with RMRRs from being placed into SI Domain"), the Intel IOMMU driver doesn't allow any devices with RMRR locked to use the identity domain. This was added to to fix the issue where the RMRR info for devices being placed in and out of the identity domain gets lost. This identity maps all RMRRs when setting up the identity domain, so that devices with RMRRs could also use it.
