sandbox: define CONFIG_64BIT as appropriate
All 64-bit architectures are supposed to define CONFIG_64BIT to support
the relevant 64-bit MMIO accessors. The sandbox architecture is a bit
of a special case, because barebox uses the toolchain default and
doesn't force a bitness. Add 64BIT as promptless symbol, which reflects
the pointer size of the target platform.
