media: v4l: rcar_fdp1: Enable compilation on Gen2 platforms

Commit 1d389714 ("[media] v4l: rcar_fdp1: add FCP dependency") fixed
a compilation breakage when the optional VIDEO_RENESAS_FCP dependency is
compiled as a module while the rcar_fdp1 driver is built in. As a side
effect it disabled compilation on Gen2 by disallowing the valid
combination ARCH_RENESAS && !VIDEO_RENESAS_FCP. Fix it by handling the
dependency the same way the vsp1 driver did in commit 19994673
("[media] vsp1: clarify FCP dependency").
