media: ov5640: add missing output pixel format setting
The output pixel format changed by set_fmt() pad operation is not correctly applied. It is intended to be restored by calling ov5640_set_framefmt() when the video stream is started. However, when the device is powered on by s_power subdev operation before the video stream is started, the current output mode setting is restored by ov5640_restore_mode() that also clears pending_mode_change flag in ov5640_set_mode(). So ov5640_set_framefmt() isn't called as intended and the output pixel format is not restored. This change adds the missing output pixel format setting in the ov5640_restore_mode() that is called when the device is powered on.
