    media: mediatek: vcodec: Use 4K frame size when supported by stateful decoder
    
    [ Upstream commit e25528e1dbe52784ac250071653104a8adc848e2 ]
    
    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.
