arm: imx: wandboard: fix compile error if CONFIG_VIDEO is deactivated

When I tried to deactivate VIDEO support for the Wandboard, it still
tried to initialize the Framebuffer and so on. That is the reason for
the added ifdefs. CONFIG_VIDEO is enabled in the configuration as default
and therefore nothing changes for the default user.

The structs mx6dl_i2c2_pad_info and mx6q_i2c2_pad_info are only available
when CONFIG_IPUV3 are set and should not be tried to access, when that
define is not defined.
