A recent patch renaming MIPI_DSI_MODE_EOT_PACKET to MIPI_DSI_MODE_NO_EOT_PACKET brought to light the misunderstanding in the current MCDE driver and all its associated panel drivers that MIPI_DSI_MODE_EOT_PACKET would mean "use EOT packet" when in fact it means the reverse.
Fix it up by implementing the flag right in the MCDE DSI driver and remove the flag from panels that actually want the EOT packet.
