[PATCH 5/6] command: Drop #ifdef for MEM_SUPPORT_64BIT_DATA

[Simon Glass]

This is defined only when __lp64__ is defined. That means that ulong is
64 bits long. Therefore we don't need to use a separate u64 type on those
architectures.

Fix up the code to take advantage of that, removing the preprocessor
conditions.

Also include the header file that defines MEM_SUPPORT_64BIT_DATA. It is
included by env.h in this file, but that might not last forever.
