imx: tpc70: Add board_boot_order() to distinguish between eMMC and SD boot
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. Signed-off-by: Lukasz Majewski <lukma@denx.de>
