[media] v4l: rcar_fdp1: add FCP dependency

Commit 4710b752 ("[media] v4l: Add Renesas R-Car FDP1 Driver") in the
v4l-dvb tree adds CONFIG_VIDEO_RENESAS_FDP1.

It calls into the FCP driver, but when there is no dependency, FCP might
be a module while FDP1 is built-in.

We have the same logic in VIDEO_RENESAS_VSP1, which also depends on
FCP not being a module when it is built-in itself.
