media: platform: mtk-mdp3: Add missing MT8188 compatible to comp_dt_ids

Browse Source 
Commit 4a81656c8e ("arm64: dts: mediatek: mt8188: Address binding
warnings for MDP3 nodes") caused a regression on the MDP functionality
when it removed the MT8195 compatibles from the MDP3 nodes, since the
MT8188 compatible was not yet listed as a possible MDP component
compatible in mdp_comp_dt_ids. This resulted in an empty output
bitstream when using the MDP from userspace, as well as the following
errors:

  mtk-mdp3 14001000.dma-controller: Uninit component inner id 4
  mtk-mdp3 14001000.dma-controller: mdp_path_ctx_init error 0
  mtk-mdp3 14001000.dma-controller: CMDQ sendtask failed: -22

Add the missing compatible to the array to restore functionality.
