Subject: [PATCH 09/30] usb: chipidea: otg: Fix kerneldoc issues relating to description of 'ci'

Firstly we add some missing descriptions.  Then we fix some formatting
issues.  Kerneldoc expects arguments to be in the format '@.*: '.  If
either the '@' or ':' is omitted, kerneldoc gets confused.

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

 drivers/usb/chipidea/otg.c:29: warning: Function parameter or member 'ci' not described in 'hw_read_otgsc'
 drivers/usb/chipidea/otg.c:82: warning: Function parameter or member 'ci' not described in 'hw_write_otgsc'
 drivers/usb/chipidea/otg.c:235: warning: Function parameter or member 'ci' not described in 'ci_hdrc_otg_init'
 drivers/usb/chipidea/otg.c:254: warning: Function parameter or member 'ci' not described in 'ci_hdrc_otg_destroy'
