Just numbering to make things consistent with reference manual. Let me know if it is worth doing then I'll send another patch with updated description otherwise not

Shall I send v4 with new description? Well if this is a cosmetic fix only, let's wait a bit so we can get rid of the "ti,hwmods" part. I'll post patches for that after -rc, so in few weeks.
