u-boot-aspeed: ECC device tree support

This moves ECC support to be device tree based. All u-boot images using
the defconfig will contain the code to run with ECC, but it will only be
enabled by systems that set the aspeed,ecc-enabled device tree property.

p10bmc is the first machine to enable ECC in this fashion.

Joel Stanley (4):
      config/ast2500: Enable RAM devices
      ram/aspeed: Use device tree to configure ECC
      ram/aspeed: Remove ECC config option
      ARM: dts: aspeed: p10bmc: Enable ECC
