[PATCH 14/30] usb: cdns3: ep0: Fix a bunch of kerneldoc issues

[Lee Jones]

Add some missing function argument descriptions for 'ep', 'desc'
and 'zlp', and correct spelling/bitrot issues surrounding the
correct spelling of present args.

Fixes the following W=1 warnings:

 drivers/usb/cdns3/ep0.c:36: warning: Function parameter or member 'zlp' not described in 'cdns3_ep0_run_transfer'
 drivers/usb/cdns3/ep0.c:236: warning: Function parameter or member 'ctrl' not described in 'cdns3_req_ep0_get_status'
