Sparse gives us the following warning on sst-firmware.c

  CHECK   sound/soc/intel/sst-firmware.c
sound/soc/intel/sst-firmware.c:39:34: warning: incorrect type in argument 1 (different address spaces)
sound/soc/intel/sst-firmware.c:39:34:    expected void volatile [noderef] <asn:2>*dst
sound/soc/intel/sst-firmware.c:39:34:    got void *
sound/soc/intel/sst-firmware.c:417:36: warning: incorrect type in argument 1 (different address spaces)
sound/soc/intel/sst-firmware.c:417:36:    expected void *dest
sound/soc/intel/sst-firmware.c:417:36:    got void [noderef] <asn:2>*
sound/soc/intel/sst-firmware.c:430:5: warning: symbol 'sst_block_module_remove' was not declared. Should it be static?

This patch removes this warning.
