build: convert sound.mak to Kconfig

There is really nothing special in these devices; they are just
ISA devices.  Instead of including them for each target,
set CONFIG_ISA_BUS to true, and make the devices default to present
whenever ISA is available.  More conversion of ISA devices will
follow.

Done with the following script:

  while read i; do
     i=${i%=y}; i=${i#CONFIG_}
     sed -i -e'/^config '$i'$/!b' -en \
            -e'a\' -e'    default y\' -e'    depends on ISA_BUS' \
          `grep -lw $i hw/*/Kconfig`
  done < default-configs/sound.mak
