[U-Boot] [PATCH] ARM: mvebu: set correct mem_size for db-88f6820-amc

[Chris Packham]

The db-88f6820-amc has four chips with 2Gb density giving a total of 1GB
DRAM. Update the board_topology_map to reflect the correct
configuration.

When I setup this board I misinterpreted 2 Gigabits as 2 Gigabytes. It
happened to work so I never noticed it was wrong until I started seeing
some unexpected mirroring of addresses.
