pcspkr: undepend of snd-pcsp

Hello.

It should be possible to build pcspkr driver together with snd-pcsp. Even though right now there is no good plan to get these drivers to work together, some things were done, namely:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=16dc42e018c2868211b4928f20a957c0c216126c
and
https://bugzilla.redhat.com/show_bug.cgi?id=448425
which looks more or less sufficient.

And there was a discussion already:
http://kerneltrap.org/mailarchive/linux-kernel/2008/4/29/1652654

The attached patch allows pcspkr to be built together with snd-pcsp.

Dmitry, could you please apply?
