- 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

Actually, there are other lines in this file greater than 80, but IMHO, it isn't a reason to continue to do that.

After that, everything looks fine for me.
