[PATCH v4 2/2] drm: bridge: ti-sn65dsi83: Disable video burst mode for LVDS stability

[Sudarshan Shetty <tessolveupstream@gmail.com>]

The current DSI configuration enables MIPI_DSI_MODE_VIDEO_BURST.
while burst mode is supported by the hardware, its use
depends on continuous clock behavior from the DSI host. In practice,
burst mode may introduce instability depending on the host controller
implementation, as the DSI link may transition to low-power state
between bursts.

Testing showed improved display stability when using non-burst mode on
affected panels.

Remove MIPI_DSI_MODE_VIDEO_BURST and use non-burst video mode.
