[PATCH] drm/panel: simple: innolux, at070tn92: specify correct pixdata edge

[Ahmad Fatoum]

Panel expects pixel data to be driven on a rising clock edge,
according to A070-92-TT-01 spec, v01, figure 3.1 on page 10/20:
http://www.webcitation.org/75IfI67Kk

This is untested on the AT070TN92, but on its Acrowise AWY-800480T70PC15A
clone, this fixes a 'dancing pixels' artifact when running modetest -s.
