To support DSI and eDP as main display connector without modifying
mtk-drm driver, we add the dynamic connector selection mechanism.

Change in v7:
1. separate 2 fixes patch from v6.
2. remove unnecessary null checking and variable.
3. move ddp_comp checking to crtc create.

Change in v6:
1. remove max_ddp_comp_nr.

Change in v5:
1. Change conn_routes array to single component enum id.

Change in v4:
1. Change variable naming from conn_route_num to num_conn_routes.
2. Change he encoder_index function return valuew from int to unsigned int.

Change in v3:
1. Change max_num comparison statement to max().

Change in v2:
1. rebase on linux-next: next-20230426
2. Fix alphabetical order and max_num condition check problem.

Change in v1:
1. based on mediatek-drm maintainer's tree / mediatek-drm-next branch:
https://git.kernel.org/pub/scm/linux/kernel/git/chunkuang.hu/linux.git/log/?h=mediatek-drm-next
