usb: common: ulpi: Fix a few kerneldoc related issues

Firstly, demote function header to standard comment block as
they are not suitable for kerneldoc.  Then provide description
for ulpi_register_driver()'s argument 'module'.  Finally rename
description for ulpi_unregister_interface()'s 'ulpi' arg.

Fixes the following W=1 warnings:

 drivers/usb/common/ulpi.c:23: warning: Function parameter or member 'ulpi' not described in 'ulpi_read'
 drivers/usb/common/ulpi.c:23: warning: Function parameter or member 'addr' not described in 'ulpi_read'
 drivers/usb/common/ulpi.c:150: warning: Function parameter or member 'module' not described in '__ulpi_register_driver'
 drivers/usb/common/ulpi.c:299: warning: Function parameter or member 'ulpi' not described in 'ulpi_unregister_interface'
 drivers/usb/common/ulpi.c:299: warning: Excess function parameter 'intrf' description in 'ulpi_unregister_interface'
