Subject: [PATCH 0/2] ensure alignment on CPU page for bo mapping

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.
