The Berkshire USB-PC Watchdog driver uses a semaphore as mutex.  Use the mutex
API instead of the (binary) semaphore.

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.

- Use timer macros to set function and data members and to modify
  expiration time.
- Use DEFINE_TIMER for single (platform dependent) watchdog timers and
  do not init them at run-time in these cases.
- del_timer_sync is common in most cases -- we want to wait for timer
  function if it's still running.

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

The PCWD cards normally use the heartbeat that is set via
the dip-switches of the card. There are only 3 switches,
thus 8 combinations that each have a certain heartbeat.
The card can however be programmed with a heartbeat from
1 till 65535 seconds. This is what our driver does: it
programs the heartbeat on the card.

There are however a lot of people that don't know that
we set the heartbeat of the watchdog card to the value
provided by the heartbeat module parameter. Instead they
think that the heartbeat value is the same as set by the
dip-switches.

This patch changes the driver so that at startup you can
take the heartbeat from the dip-switches. You do this
by setting the heartbeat module parameter to 0. This
patch also makes this the default behaviour.
