Watchdog drivers need to support rearming the watchdog in contexts which
are not permitted to sleep.  Only use the IPMI watchdog with backends
which poll driver-initiated requests to meet this requirement.

In practice this means that watchdogs will no longer be used on systems
that use the SSIF backend.
