[PATCH 16/21] media: ov5640: Disable s_frame_interval in MIPI mode

[Jacopo Mondi <jacopo@jmondi.org>]

When the sensor is operated in MIPI mode, the frame rate configuration
is performed by tuning the frame blanking times and not by the
s_frame_interval subdev operation.

Disallow enum/s/g_frame_interval if the chip is used in MIPI mode.

While at it re-indent one function which whose parameters were wrongly
aligned.
