[PATCH] watchdog: at91sam9: keep watchdog running in idle mode

[Sylvain Rochet]

Since turning on idle-halt in commit 5161b31dc39a (watchdog:
at91sam9_wdt: better watchdog support"), SoCs compatible with
at91sam9260-wdt not using a device tree no longer reboot if the watchdog
times out while the CPU is in idle state. Removing the
AT91_WDT_WDIDLEHLT flag that was set by default fixes this.
