drm/amdkfd: Fix ATS capablity was not reported correctly on some APUs
[ Upstream commit 44d8cc6f1a905e4bb1d4221a898abb0d7e9d100a ]
Because CRAT_CU_FLAGS_IOMMU_PRESENT was not set in some BIOS crat, we
need to workaround this.
For future compatibility, we also overwrite the bit in capability according
to the value of needs_iommu_device.
