[PATCH 76/87] drm/amd/display: drop ASSERT() if eDP panel is not connected

From: Zhan Liu <zhan.liu at amd.com>

For boards that support eDP but do not have a physical eDP
display connected an ASSERT will be thrown. This is not a
critical failure and shouldn't be treated as such.

Drop the assertion.
