[PATCH] cmd: mmc: modify more readable about hwpartition usage

[Jaehoon Chung]

Modified more readable about hwpartition usage.
Because it's difficult to understand how to use its command.
The arguments didn't optional.
mmc hwpartition needs to pass <USER> <GP> <MODE> as arguments.
Description about each arguments what is required is the below:
 USER - <user> <enh> <start> <cnt> <wrrel> <{on|off}>
 GP   - <{gp1|gp2|gp3|gp4}> <cnt> <enh> <wrrel> <{on|off}>
 MODE - <{check|set|complete}>
