Subject: [PATCH 17/30] usb: chipidea: udc: Fix a few kerneldoc issues

Descriptions were missing for 'ci' almost throughout.  There was
one instance of over-documenting.  Finally one function argument
was incorrectly documented (probably down to bitrot).

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

 drivers/usb/chipidea/udc.c:245: warning: Function parameter or member 'ci' not described in 'hw_port_is_high_speed'
 drivers/usb/chipidea/udc.c:271: warning: Function parameter or member 'ci' not described in 'hw_test_and_clear_intr_active'
 drivers/usb/chipidea/udc.c:285: warning: Function parameter or member 'ci' not described in 'hw_test_and_clear_setup_guard'
 drivers/usb/chipidea/udc.c:296: warning: Function parameter or member 'ci' not described in 'hw_test_and_set_setup_guard'
 drivers/usb/chipidea/udc.c:321: warning: Function parameter or member 'ci' not described in 'hw_usb_reset'
 drivers/usb/chipidea/udc.c:628: warning: Excess function parameter 'ci' description in 'free_pending_td'
 drivers/usb/chipidea/udc.c:655: warning: Function parameter or member 'hwep' not described in '_hardware_dequeue'
 drivers/usb/chipidea/udc.c:655: warning: Excess function parameter 'gadget' description in '_hardware_dequeue'
