[Intel-gfx] [PATCH v2 3/7] drm/i915: add MISSING_CASE annotation to ibx_digital_port_connected

[Jani Nikula]

With the case added for eDP on port A (always connected from this
function's point of view), we should not be hitting any of the default
cases in ibx_digital_port_connected, so add MISSING_CASE annotation.
