[PATCH 1/1][SRU][U/OEM-5.10] drm/i915/tgl: Fix typo during output setup

[Koba Ko]

From: Imre Deak <imre.deak at intel.com>

BugLink: https://bugs.launchpad.net/bugs/1914020

Fix a typo that led to some MST short pulse event handling issue (the
short pulse event was handled for both encoder instances, each having
its own state).

Fixes: 1d8ca002456b6 ("drm/i915: Add PORT_TCn aliases to enum port")
