kbuild: remove OSS pointless hex default

Greg Banks:

The symbol CONFIG_SOUND_CMPCI_FMIO is declared with a "hex" statement,
immediately preceded by a "define_hex" with the same value as the
default value from the "hex".  In config and xconfig, this has no effect;
in menuconfig it prevents the user selecting any value other than the
default.
