This patch fixes the DP AUX CH timeouts observed during CI runs causing
CI Failures on a specific PCI device. This issue was fixed previously
by adding a quirk but looks like we need to increase this delay even more
in order to get rid all the DP AUX CH timeouts.
Fixes: c99a259b4b5192ba ("drm/i915/edp: Add a T12 panel delay quirk to fix
DP AUX CH timeouts")
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=101144
