While working on adding more boards I noticed that we lack a config for the 512M cubieboard, and that some of the new boards which I want to add also have 512M and 1G variants, rather then adding 2 defconfig's for all of these, lets switch the exising boards which have both a 512M and 1024M variant over to the sun4i dram autoconfig code. This also drops the foo_RAMSIZE_defconfig variants of boards where we currently have 2 separate configs already. Note: 1) The newly introduced CONFIG_DRAM_EMR1 kconfig value is not used with a value other then its default for now, but we need this to be configurable to support some new boards with auto dram config. 2) We always set all CONFIG_DRAM_foo values in defconfigs, even if they match the defaults, this is done to make it more clear what values are used for a certain board. This has been tested on a Mele A1000, Mini-X and a Cubieboard, all 1G variants, the dram autoconfig code has also been tested on a 512M mk802 (a defconfig for the mk802 is added in a later patch).
