dt-bindings: display: fix panel warnings

Fix following type af warnings in the panel bindings:

Warning (unit_address_vs_reg): /example-0/dsi/panel: node has a reg or ranges property, but no unit name
Warning (unit_address_vs_reg): /example-0/dsi@ff450000: node has a unit name, but no reg property

Removing the "@xxx" from the node name fixed first warning.
Adding a missing reg property fixed the second warning

v2:
  - renamed mdss_dsi to dsi in panel-simple-dsi.yaml (Rob)
