This is because playinit() is declared with a (void) argument list, but
defined with an empty argument list. Make the definition match the
declaration.

Remove splclock(). It's not useful to keep.

splclock is used in one driver (spkr) to control access to
timer_spkr_* routines. However, nothing else does. So it shows no
useful locking info to someone that would want to lock spkr.

NOTE: I think there's races with timer_spkr_{acquire,release} since
there's no interlock in those routines, despite there being a spin
lock to protect the clock. Current other users appear to use no extra
locking protocol, though they themselves appear to be at least
attempting to make sure that only a single thread calls these
routines. I suspect the right answer is to update these routines to
take/release the clock spin lock since they are short and to the
point, but that's beyond the scope of this commit.

Remove unneeded checks of device unit number from speaker(4).

Replace all calls to minor() with dev2unit().

After I removed all the unit2minor()/minor2unit() calls from the kernel
yesterday, I realised calling minor() everywhere is quite confusing.
Character devices now only have the ability to store a unit number, not
a minor number. Remove the confusion by using dev2unit() everywhere.

This commit could also be considered as a bug fix. A lot of drivers call
minor(), while they should actually be calling dev2unit(). In -CURRENT
this isn't a problem, but it turns out we never had any problem reports
related to that issue in the past. I suspect not many people connect
more than 256 pieces of the same hardware.

The "free-lance" timer in the i8254 is only used for the speaker
these days, so de-generalize the acquire_timer/release_timer api
to just deal with speakers.

The new (optional) MD functions are:
timer_spkr_acquire()
timer_spkr_release()
and
timer_spkr_setfreq()

the last of which configures the timer to generate a tone of a given
frequency, in Hz instead of 1/1193182th of seconds.

Drop entirely timer2 on pc98, it is not used anywhere at all.

Move sysbeep() to kern/tty_cons.c and use the timer_spkr*() if
they exist, and do nothing otherwise.

Remove prototypes and empty acquire-/release-timer() and sysbeep()
functions from the non-beeping archs.

This eliminate the need for the speaker driver to know about
i8254frequency at all. In theory this makes the speaker driver MI,
contingent on the timer_spkr_*() functions existing but the driver
does not know this yet and still attaches to the ISA bus.

Syscons is more tricky, in one function, sc_tone(), it knows the hz
and things are just fine.

In the other function, sc_bell() it seems to get the period from
the KDMKTONE ioctl in terms if 1/1193182th second, so we hardcode
the 1193182 and leave it at that. It's probably not important.

Change a few other sysbeep() uses which obviously knew that the
argument was in terms of i8254 frequency, and leave alone those
that look like people thought sysbeep() took frequency in hertz.

This eliminates the knowledge of i8254_freq from all but the actual
clock.c code and the prof_machdep.c on amd64 and i386, where I think
it would be smart to ask for help from the timecounters anyway [TBD].

Rename timer0_real_max_count to i8254_real_max_count and make it static.
Rename timer_freq to i8254_freq and make it a loader tunable.

Now that tone & delay times are correct (independent of hz), adjust
playtone() so that it uses times of 1/100ths of a second.

Now 'time echo T60ABC >/dev/speaker' takes ~3 seconds.
