ASoC: Intel: Fix sparse warnings for firmware loader

Sparse gives us the following warnings 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 *
