I know we have this alias in mt8173.dtsi, but I don't understand what 
they are for. Do you know?

The mtk_disp_rdma platform driver uses mtk_ddp_comp_get_id() to identify
the specific RDMA instance, which calls of_alias_get_id(). The core code
needs to know which RDMA is which to correctly set up the display data
paths.

Can you please rebase on a recent kernel version. mt2701-mmsys node is 
already present.
