commit f9cdf4130671d767071607d0a7568c9bd36a68d0 upstream.
intel_dsi->ports contains bitmask of enabled ports and correspondingly
logic for selecting port for VBT packet sending must use port specific
bitmask when deciding appropriate port.
Fixes: 08c59dde71b7 ("drm/i915/dsi: fix VBT send packet port selection for ICL+")
