[PATCH] fix book E watchdog to take WDIOC_SETTIMEOUT arg in seconds

Hi Chris,

Added with some small changes to keep checkpatch happy. (removed trailing spaces + changed sizeof(struct watchdog_info) to sizeof(ident) and changed some spaces in tabs).

Now we only need someone that can look at the CONFIG_4xx cases still :-)

Kind regards,
Wim.
