Subject: [PATCH v2] drm/panel: otm8009a: allow using non-continuous dsi clock

From: Antonio Borneo <[email protected]>

The panel is able to work when dsi clock is non-continuous, thus
the system power consumption can be reduced using such feature.

Add MIPI_DSI_CLOCK_NON_CONTINUOUS to panel's mode_flags.

Changes in v2:
- Added my signed-off
