Add JSON output for 'ethtool -m' / --module-info, following the
guideline below:

1. Fields with description, will have a separate description field.
2. Fields with units, will have a separate unit field.
3. ASCII fields will be presented as strings.
4. On/Off is rendered as true/false.
5. Yes/no is rendered as true/false.
6. Per-channel fields will be presented as array, when each element
   represents a channel.
7. Fields that hold version, will be split to major and minor sub
   fields.

This patchset suppose to extend [1] to cover all types of modules.
