usb: phy: phy: Fix-up a whole bunch of formatting issues

Kerneldoc expects arg descriptions to be in the format '@.*: '.  If either
the '@' or the ':' is omitted then kerneldoc complains that the description
is missing.  Add the missing ':'s here.

Also provide a new description for 'event'.

Fixes the following kernel build W=1 warnings:
