[PATCH v11 0/9] Add connector dynamic selection capability

[Jason-JH.Lin <jason-jh.lin@mediatek.com>]

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

Change in v11:
1. move some global variable to a scope.
2. move mtk_drm_crtc_update_output() after pm_runtime_resume_and_get().
3. move return 0 when error occurred into mtk_drm_find_comp_in_ddp_conn_path().

Change in v10:
1. rebase to Linux 6.6-rc3.
2. separate the common part of adding encoder_index interface for ddp_comp
   to a single patch.
3. separate the DP_INTF0 support dynamic selection to a single patch.
4. add the array size while allocating ddp_comp array in mtk_crtc.
5. add some comment for marking encoder_index to -1.

Change in v9:
1. change subject title and [PATCH v11 5/7] title.
2. separate [PATCH v11 4/7]
   and [PATCH v11 5/7].
3. fix typo and some grammar problems in commit message.

Change in v8:
1. add mtk_drm_crtc_path enum to replace array index of all_drm_priv.
2. separate add encoder_index function to another patch.
3. separate add dpi and dsi encoder_index function implementation to
   another patch.
4. separate add dsi conn_routes support to another patch.
5. set encoder_index to -1 if comp->dev doesn't not exist and add
   (encoder_index >= 0) checking before assigning conn_routes.
6. move conn_routes statement to the end of mtk_drm_crtc_create.

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
