Don't need to query error count and error address on harvest umc nodes.
v2: Fix code bug, use active_mask instead of harvsest_config
and remove unnecessary argument in LOOP macro.
v3: Leave adev->gmc.num_umc unchanged.

Since commit ee6d3dd4ed ("driver core: make kobj_type constant.")
the driver core allows the usage of const struct kobj_type.
Take advantage of this to constify the structure definitions to prevent
modification at runtime.

If CONFIG_DRM_AMDGPU=y and CONFIG_DRM_AMD_DC is not set,
gcc complained about unused-function :
drivers/gpu/drm/amd/amdgpu/amdgpu_discovery.c:1705:13: error: ‘amdgpu_discovery_set_sriov_display’ defined but not used [-Werror=unused-function]
static void amdgpu_discovery_set_sriov_display(struct amdgpu_device *adev)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To fix this error, use CONFIG_DRM_AMD_DC to wrap
the definition of amdgpu_discovery_set_sriov_display().

virtual display is enabled unconditionally in SR-IOV, but
without specifying the virtual_display module, the number
of crtcs defaults to 0. Set a single display by default
for SR-IOV if the virtual_display parameter is not set.
Only enable virtual display by default on SR-IOV on asics
which actually have display hardware.

If discovery is set to 2 in module parameters explicitly, the
intention is to use the discovery file in FW rather than the one in
BIOS, usually because the latter is incorrect. This patch to force
read discovery file if set discovery=2.

SRIOV needs to initialize mmsch instead of multimedia engines
directly. So currently remove them for SR-IOV until the code and
firmwares are ready.

[Why]
under SR-IOV, the nbio doorbell range will be defined by PF. So VF
nbio doorbell range registers will be blocked. It will cause violation
if VF access those registers directly.
[How]
create an nbio_v4_3_sriov_funcs for sriov nbio_v4_3 initialization to
skip the setting for the doorbell range registers.

Align RDNA2.x with other asics. One HDP bit per SDMA instance,
aligned with firmware. This is effectively a revert of
commit 369b7d04ba ("drm/amdgpu/nbio2.3: don't use GPU_HDP_FLUSH bit 12").
On further discussions with the relevant hardware teams,
re-align the bits for SDMA.

structure sizes to make sure we don't get into a
