ShengYi Hung 2b74ff5fce ichwd: introduce i6300esbwd watch dog driver
The intel 6300ESB watchdog is a special ICH-based watchdog device with a
different interface.
QEMU implements this watchdog for x86 systems.

This change enables watchdog mode (rather than free-running mode) and
introduces 1 sysctl:
- hw.i6300esbwd.0.locked: locks the watchdog register after the event is
triggered, preventing it from being disabled until a hard reset.

This feature has been tested on a Vultr AMD guest machine and local qemu
machine.
