drm/bridge: ti-sn65dsi83: Do not generate HFP/HBP/HSA and EOT packet

Browse source 
[ Upstream commit f4d324fb5628773907dd90342d18f978bd9a6d09 ]

[ Upstream commit ca161b259c ]

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.
