[PATCH for next 09/15] ARM: phytec-som-imx6: fix bootsource for phyCORE-i.MX6

[Stefan Christ]

The phyCORE-i.MX6 has either a NAND or EMMC storage device and an
external SD-Card interface. The automatic bootsource detection in the
barebox environment should reflect that.

- If the board was booted from the external SD-Card interface, it should
  continue loading the kernel and device tree from it.

- If the board was booted from EMMC, it should load kernel and device
  tree from the boot partition on the EMMC.
