drm/amdgpu: optimize VRAM allocation when using drm buddy

2023-02-23T22:35:58+00:00

Since the VRAM manager changed from drm mm to drm buddy. It's
not necessary to allocate 2MB aligned VRAM for more than 2MB
unaligned size, and then do trim. This method improves the
allocation efficiency and reduces memory fragmentation.
