usb: chipidea: udc: Help out kerneldoc headers that have tried, demote the others

Browse Source 
Help with adding the odd description where they have been omitted or
where the format isn't quite right.  Demote all function headers which
are lacking any attempt of describing their arguments.

Fixes the following W=1 kernel build warning(s):
