hwmon: (adm1177) Fix kerneldoc attribute formatting

Kerneldoc expects attributes/parameters to be in '@*.: ' format.

Also fix repeated word "the the".

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

 drivers/hwmon/adm1177.c:40: warning: Function parameter or member 'client' not described in 'adm1177_state'
 drivers/hwmon/adm1177.c:40: warning: Function parameter or member 'reg' not described in 'adm1177_state'
 drivers/hwmon/adm1177.c:40: warning: Function parameter or member 'r_sense_uohm' not described in 'adm1177_state'
 drivers/hwmon/adm1177.c:40: warning: Function parameter or member 'alert_threshold_ua' not described in 'adm1177_state'
 drivers/hwmon/adm1177.c:40: warning: Function parameter or member 'vrange_high' not described in 'adm1177_state'
