[PATCH v3 07/12] drm/bridge: tc358768: Print logical values, not raw register values

[Tomi Valkeinen]

The driver debug prints DSI related timings as raw register values in
hex. It is much more useful to see the "logical" value of the timing,
not the register value.

Change the prints to print the values separately, in case a single
register contains multiple values, and use %u to have it in a more human
consumable form.
