drm/bridge: ti-sn65dsi83: Do not generate HFP/HBP/HSA and EOT packet
Do not generate the HS front and back porch gaps, the HSA gap and
EOT packet, as per "SN65DSI83 datasheet SLLSEC1I - SEPTEMBER 2012
- REVISED OCTOBER 2020", page 22, these packets are not required.
This makes the TI SN65DSI83 bridge work with Samsung DSIM on i.MX8MN.
