drm/panel: simple: add support for overriding the pixel clock polarity

The Ka-Ro electronics MB7 baseboard has an on-board LCD->LVDS
converter that requires a fixed pixelclk polarity, no matter what the
panel's display_mode specifies. Add an option to override the pixelclk
polarity defined in the panel's display_mode via DTB.
