Subject: drm/amdgpu: remove gart.ready flag

Git-commit: 1b08dfb889b2c584b444538c9500af24ba0a6dc7
Patch-mainline: v5.18-rc1

That's just a leftover from old radeon days and was preventing CS and GART
bindings before the hardware was initialized. But nowdays that is
perfectly valid.
The only thing we need to warn about are GART binding before the table
is even allocated.
