In AMDGPU driver, the bo mapping should always align to CPU page or
the page table is corrupted.

The first patch is cherry-picked from Loongson community, which sets a
suitable dev_info.gart_page_size so Mesa will handle the alignment
correctly.

The second patch is added to ensure an ioctl with unaligned parameter to
be rejected -EINVAL, instead of causing page table corruption.

The patches should be applied for drm-next.
