[PATCH] build sound/sound_firmware.c only for OSS
All sound/sound_firmware.c contains is mod_firmware_load() that is a legacy
API only used by some OSS drivers.
This patch builds it into an own sound_firmware module that is only built
depending on CONFIG_SOUND_PRIME making the kernel slightly smaller for ALSA
users.
