[PATCH v2 2/2] arm64: mvebu: a37xx: Add support for EspressoBIN with eMMC

[Andre Heider]

From: Konstantin Porotchkin <kostap at marvell.com>

Add support for additional EspressoBIN board with installed
eMMC device (U11).
Starting from this patch the DEVICE_TREE= must be added to
"make" in order to distinguish between platforms wth and without
eMMC on board.
Regualr (no eMMC) EspressoBIN builds should use DTS file named
armada-3720-espressobin and build for boards with eMMC installed
the DTS named armada-3720-espressobin-emmc.
The default device tree string is now removed from
mvebu_espressobin-88f3720_defconfig config file.
Update build documentation accordingly.
