media: ov5640: set correct default format for CSI-2 mode

In commit a89f14bb ("media: ov5640: Split DVP and CSI-2 formats"),
it splits format list for DVP and CSI-2 mode, but the default format
defined in commit 90b0f355 ("media: ov5640: Implement init_cfg")
is only supported by DVP mode, so define a new default format for
CSI-2 mode.
