Remove empty comments from code

[lorenzschmid]

With the changes from #61, descriptions were removed from being printed in the code. If the field contains no comment, the string (missing comment) gets printed. Having very little comments in our cheby maps, we have now the (missing comment) all over without adding much information to the code.

This pull request improves #61 by printing the name of the field if no comment is present or skipping to print anything altogether. See the regenerated testfiles for a comparison.

Yes, I understand your point. But I fear this could be improved:

For

/* (comment missing) */
#define SAME_LABEL_REG_NO_FIELDS 0x0UL

I would emit as a comment:

/* register no_fields */
#define SAME_LABEL_REG_NO_FIELDS 0x0UL

as the name of the element is not that immediate to see (just /* no_fields */ would also be ok).

However, for:
``
struct b2 {

• /* [0x0]: REG (rw) (comment missing) */

• /* [0x0]: REG (rw) r3 */
  uint32_t r3;
  } b2;

I am not sure it is worth printing again the name of the register in the comment (but that's ok too).

Both proposals are fine with me. I changed them in 799a491 and updated the pull request.
