To reduce code duplicate and increase code readability use WDT core
code to handle WDT interface.
Remove io_lock as the WDT core uses mutex to lock each wdt device.
Remove wdt_state as the WDT core tracks state with its own variable.
The watchdog_init_timeout() can read timeout value from timeout-sec
property if the passed value is out of bounds. The heartbeat is
initialized in next way. If heartbeat is not set thought module
parameter, try to read it's value from WDT node timeout-sec property.
If node has no one, use default value.
The heartbeat is hold in wdd->timeout by WDT core, so use it in
order to set timeout period.

Pls note, that this patch contains both changes in platform and driver
code to fix regression reported by Sekhar Nori on v2 of this series and
caused by driver name changing.
Is it ok?
It can be splitted, but then both patches will introduce regression by
itself and thing will work only if both of them will be applied together.
