drm/amdkfd: Centralize IOMMUv2 code and make it conditional
dGPUs work without IOMMUv2. Make IOMMUv2 initialization dependent on
ASIC information. Also allow building KFD without IOMMUv2 support.
This is still useful for dGPUs and prepares for enabling KFD on
architectures that don't support AMD IOMMUv2.
v2:
* Centralize IOMMUv2 code to avoid #ifdefs in too many places
v3:
* Imply AMD_IOMMU_V2 in Kconfig
