To reduce code duplicate and increase code readability use WDT core

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.

So this still causes a regression because the clk_get()
fails due to the changed device name. Please fold this
patch in (tested on DM365, compiled on rest).

Also, the change in device name (while needed) does not seem
to be related to usage of wdt core. Can you may be split
that change into a separate patch?


Given all the trouble with it, I think that would be a good idea.

Guenter


Ok, I'll split it for convenience.
