Do not generate the HS front and back porch gaps, the HSA gap and
EOT packet, as per "SN65DSI83 datasheet SLLSEC1I - SEPTEMBER 2012

This makes the TI SN65DSI83 bridge work with Samsung DSIM on i.MX8MN.

I have successfully used this driver with a Raspberry Pi CM4. The VC4
DSI driver does not seem to support the newly added flags, so this patch
shouldn't have any effect there.

Indeed, I noticed very few controllers support those flags . Maybe over time we will get more of the support on controller side.
