arm: mvebu: Espressobin: Enable 'mtd' command and define SPI NOR partitions

Browse Source 
U-Boot now supports parsing SPI NOR partitions from Device Tree. So enable
'mtd' command support for Espressobin board and define partition layout in
U-Boot Espressobin DTS file. Access to SPI NOR via 'sf' command is old
method and 'mtd' command is now preferred variant.

From include file remove '#define CONFIG_MTD_PARTITIONS' as this option is
now defined and enabled in defconfig file. This change is required to fix
compile error:

      CC      arch/arm/lib/asm-offsets.s
    In file included from include/config.h:4,
                     from include/common.h:16,
                     from lib/asm-offsets.c:14:
    include/configs/mvebu_armada-37xx.h:63: warning: "CONFIG_MTD_PARTITIONS" redefined
     #define CONFIG_MTD_PARTITIONS  /* required for UBI partition support */

    include/generated/autoconf.h:44: note: this is the location of the previous definition
     #define CONFIG_MTD_PARTITIONS 1

After enabling support for mtd command, output from 'mtd list' on
Espressobin board is:

    => mtd list
