MA-9140 Add variant as imx6ul_pico or imx6ul_iopb depending on the board

The bootloader is currently reporting the variant (ie imx6ul_pico) for
the product variable and not reporting a product variable. This needs to
be changed to report product=imx6ul for both boards and
variant=imx6ul_pico or imx6ul_iopb depending on the board.
