[REVIEW,02/11] tvp7002: use dv_timings structs instead of presets.

Commit Message

From: Hans Verkuil <[e-mail]>

In the functions tvp7002_mbus_fmt(), tvp7002_log_status and tvp7002_probe()
we should use the dv_timings data structures instead of dv_preset data
structures and functions.

This is the second step towards removing the deprecated preset support of this
driver.
