After the recent cleanup, the functionalities provided by the previous
kfd_kernel_queue_*.c are actually all packet manager related. So rename
them to reflect that.

The only difference that CIK kernel queue functions are different from
VI is avoid allocating eop_mem. We can achieve that by using a if
condition.

The kernel queue functions for v9 and v10 are the same except
pm_map_process_v* which have small difference, so they should be reused.
This eliminates the need of reapplying several patches which were
applied on v9 but not on v10, such as bigger GWS and more than 2
SDMA engine support which were introduced on Arcturus.

KFD (kernel fusion driver) is the kernel driver
for the compute backend for usermode compute
stack.

Since KFD is only supported by single GPU driver, it makes sense to merge
amdgpu and amdkfd into one module. This patch is the initial step: merge
Kconfig and Makefile.

v2: also remove kfd from drm Kconfig

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
