drm/panel: samsung-s6d7aa0: drop DRM_BUS_FLAG_DE_HIGH for lsl080al02

[ Upstream commit 62b143b5ec4a14e1ae0dede5aabaf1832e3b0073 ]

It turns out that I had misconfigured the device I was using the panel
with; the bus data polarity is not high for this panel, I had to change
the config on the display controller's side.

Fix the panel config to properly reflect its accurate settings.
