drm/i915/dsi: fix VBT send packet port selection for dual link DSI

Commit Message

Mikko Kovanen Nov. 26, 2022, 1 p.m. UTC

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.
