commands: implement and use parse_assignment helper

We have the split by '=' snippet at multiple locations that parse
key=value pairs. Consolidate them to a single location. This makes code
a bit easier to read at the cost of an extra 8 bytes (LZO-compressed
THUMB2 barebox, static inline version is bigger).

No functional change.
