Pull second set of watchdog updates from Wim Van Sebroeck:
"This changeset contains following changes:
* Add support for multiple watchdog devices. We use dynamically
allocated device id's for this.
* Add locking into the generic watchdog infrastructure.
* Add support for dynamically allocated watchdog_device structs so
that we can deal with devices that get unbound.
* convert following drivers to the generic watchdog framework:
sch5627, sch5636 and sp805_wdt.
* Add DA9052/53 PMIC watchdog support
* Fix printk format warnings for iTCO_wdt.c"
