drm/i915/edp: Increase T12 panel delay to 900 ms to fix DP AUX CH timeouts

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.

DP AUX CH timeouts")
