This MIPI-DSI LCD panel must be connected to something.  According to
scarce web data it supports two channels and it is already used like
this in DTS.  Reported by dtbs_check:

  rockchip/rk3399-gru-scarlet-inx.dtb: panel@0 (innolux,p097pfg): 'ports' does not match any of the regexes: '^pinctrl-[0-9]+$'
