The TQMa6ul upstream device trees contain aliases which swap the order
of the mmc nodes, so what used to be mmc0 has now become mmc1 and vice
versa. With this mmc0 now is the eMMC and mmc1 is the SD card.
Introduce a imx6ul.dtsi which adds barebox,bootsource-mmcx aliases so
that bootsource_get_instance() matches our mmc numbering again. Also
register the eMMC BBU handler on /dev/mmc0 and the SD BBU handler on
/dev/mmc1.
