snd-pcsp: adjust help texts to frighten users

Added the warning text to the help of snd-pcsp about the possible problem
with this driver so that user can know of the problem in advance.

Also, removed the obsoleted text about ancient pc-speaker patch in
CONFIG_SOUND help.

+          WARNING: if you already have a soundcard, enabling this
+          driver may lead to a problem. Namely, it may get loaded
+          before the other sound driver of yours, making the
+          pc-speaker a default sound device. Which is likely not
+          what you want. To make this driver play nicely with other
+          sound driver, you can add this into your /etc/modprobe.conf:
+          options snd-pcsp index=2

           You don't need this driver if you only want your pc-speaker to beep.
           You don't need this driver if you have a tablet piezo beeper
           in your PC instead of the real speaker.
