sound: Retire OSS
Since no complaints have been raised after disabling the build of OSS (Open Sound System) by the commit 31cbee6a5611 ("sound: Disable the build of OSS drivers"), let's finally drop the whole code and documentation. Some glue codes are still left intact since sound/oss/dmasound stuff remains -- which is an independent implementation solely for m68k, and it's not covered by ALSA yet. Also, a couple of API header files (linux/sound.h and linux/soundcard.h) are kept remaining as well, since the OSS API itself is still supported by ALSA OSS emulation, and applications can refer to these. Where we're at it, some help texts in the top-level Kconfig are adjusted, too (who still needs to specify I/O port in kbuild nowadays?).
