drm/bridge: tc358768: Support non-continuous clock

The driver prints a warning if MIPI_DSI_CLOCK_NON_CONTINUOUS is set, and
falls back to continuous clock mode. This was added in commit
fbc5a90e82c1 ("drm/bridge: tc358768: Disable non-continuous clock mode").

However, there have been multiple changes to the driver since then, and
at least in my setup, non-continuous clock mode works: I can see an
image on the panel, and I can see the clock lanes being non-continuous
with an oscilloscope.

So, let's enable MIPI_DSI_CLOCK_NON_CONTINUOUS support.
