arm: mvebu: Espressobin: Detect presence of emmc at runtime
Try to initialize emmc in board_late_init() and if it fails then we know
that emmc device is not connected.
This allows to use in U-Boot just one DTS file for all Espressobin variants
and also to correctly set fdtfile env variable for Linux kernel.
