ACPI / watchdog: Fix off-by-one error at resource assignment

ACPI / watchdog: Fix off-by-one error at resource assignment

BugLink: http://bugs.launchpad.net/bugs/1759655
commit b1abf6fc49829d89660c961fafe3f90f3d843c55 upstream.

The resource allocation in WDAT watchdog has off-one-by error, it sets
one byte more than the actual end address.  This may eventually lead
to unexpected resource conflicts.
