[U-Boot] [PATCH v3 3/9] imx: tpc70: Add board_boot_order() to distinguish between eMMC and SD boot

[sbabic at denx.de]

> The TPC70 can boot from SD card (debug/development) and eMMC (production).
> The board_boot_order() function provides a run time check for the device
> from which one wants to boot (it is selected by GPIO pins setup).
> Moreover, a fallback to SD card is provided if the detection is not
> possible or working properly.
