Subject: [PATCH] insert wdt kernel modules when watchdog is active

When watchdog is enabled in 1st kernel, then crash dump in kdump
kernel will be interrupted if watchdog is timeout. Since some
wdt drivers can stop the watchdog when its driver is loaded,
e.g iTCO_wdt, this can benefit crash dump.

Add watchdog driver which is active in system to initramfs, its
loading can stop watchdog.

For now, put this adding in 99kdumpbase.
