Some watchdog drivers initialize global spinlocks in module's init function
which is tolerable, but some do it in PCI probe function.  So, switch to
static initialization to fix theoretical bugs and, more importantly, stop
giving people bad examples.

move watchdog tree from drivers/char/watchdog to drivers/watchdog.
Signed-off-by: NWim Van Sebroeck <wim@iguana.be>

It seems that some watchdog drivers are doing following mistake:

	rv = misc_register();
	if (rv < 0)
		return rv;
	rv = request_region();
	if (rv < 0) {
		misc_deregister();
		return rv;
	}

But, right after misc_register() returns, misc device can be opened and
ioctls interacting with hardware issued, and driver can do outb() to
port it doesn't own yet, because request_region() is still pending.

Here is my patch, compile-tested only.

change default=CONFIG_WATCHDOG_NOWAYOUT in the module parameter
for nowayout by it's real value (0 or 1) by using:
__MODULE_STRING(WATCHDOG_NOWAYOUT)

The last argument of module_param is permissions, not default value.

Mark the static struct file_operations in drivers/char as const.  Making
them const prevents accidental bugs, and moves them to the .rodata section
so that they no longer do any false sharing; in addition with the proper
debug option they are then protected against corruption..
