watchdog: at91sam9_wdt: Fix WDT setup in at91_wdt_start()

This patch fixes the timer register setup in at91_wdt_start() to
correctly configure the register again. The input timeout value is
now in milli-seconds instead of seconds with the new watchdog API.
Make sure to take this into account and only use a max timeout
value of 16 seconds as appropriate for this SoC.

Also the check against a lower timeout value than 0 is removed. This
check makes no sense, as the timeout value is unsigned.
