ARM: dts: aspeed: minipack: Update 64MB FMC flash layout
Set 64Mb FMC flash layout in Minipack device tree explicitly because the flash layout was removed from "ast2500-facebook-netbmc-common.dtsi". Please note "data0" partition' size is updated to 4MB to be consistent with other Facebook OpenBMC platforms.
