After commit b018be06f3c7 ("media: mediatek: vcodec: Read max resolution from dec_capability"), the stateful video decoder driver never really sets its output frame size to 4K. Parse the decoder capability reported by the firmware, and update the output frame size in mtk_init_vdec_params to enable 4K frame size when available.
