[Why]
Bump into calcReducedBlankingTiming because of mode query failed.
In this function,
timing.displayColorDepth == DISPLAY_COLOR_DEPTH_UNDEFINED.
Then req_bw == 0 because of bits_per_channel == 0.
So decide edp link settings, use default RBRx1 for special timing.

[How]
Set default bits_per_channel is 8.

Without debugfs, the compiler notices one function that is not used at
all:

drivers/gpu/drm/amd/amdgpu/amdgpu_fw_attestation.c:123:12: error: unused function 'amdgpu_is_fw_attestation_supported' [-Werror,-Wunused-function]

In fact the static const amdgpu_fw_attestation_debugfs_ops structure is
also unused here, but that warning is currently disabled.

Removing the #ifdef check does the right thing and leads to all of this
code to be dropped without warning.

Previously we accepted non-linear buffers for the cursor plane. This
results in bad output, DC validation failures and oops.

Make sure the FB uses a linear layout in the atomic check function.

The GFX8- check is inspired from ac_surface_set_bo_metadata in Mesa.
The GFX9+ check comes from convert_tiling_flags_to_modifier.
