Uwe Kleine-König 757cd94ac8 rtc: pcf2127: only use watchdog when explicitly available 
commit 71ac13457d9d1007effde65b54818106b2c2b525 upstream.

Most boards using the pcf2127 chip (in my bubble) don't make use of the
watchdog functionality and the respective output is not connected. The
effect on such a board is that there is a watchdog device provided that
doesn't work.

So only register the watchdog if the device tree has a "reset-source"
property.
