ASoC: SOF: build compression interface into snd_sof.ko

With CONFIG_SND_SOC_SOF_COMPRESS=m, the compression code is
not built into a the main SOF driver when that is built-in:

x86_64-linux-ld: sound/soc/sof/ipc.o: in function `ipc_stream_message':
ipc.c:(.text+0x5a2): undefined reference to `snd_sof_compr_fragment_elapsed'
x86_64-linux-ld: sound/soc/sof/topology.o: in function `sof_dai_load':
topology.c:(.text+0x32d1): undefined reference to `snd_sof_compr_init_elapsed_work'
x86_64-linux-ld: topology.c:(.text+0x32e1): undefined reference to `snd_sof_compr_init_elapsed_work'

Make this a 'bool' symbol so it just decides whether the
code gets built at all.
