- Rename OVL_ADAPTOR_TYPE_RDMA to OVL_ADAPTOR_TYPE_MDP_RDMA
  to align the naming rule of mtk_ovl_adaptor_comp_id.
- Sort components' names in alphabetical order
- Sort device table in alphabetical order
- Add sentinel to device table

I agree, but this commit should come before [12/14] of this series.

Got it. Since [12/14] removed many lines that use component ID/type
(for example, in mtk_ovl_adaptor_clk_enable() or
mtk_ovl_adaptor_add_comp()), if this commit has to move before that,
should I still modify them and delete them in [12/14]? Thanks.

Every commit has to work on its own, so you first perform the renaming in
one commit, then you modify and delete.
