In configurations with CONFIG_SND_SOC_INTEL_SKYLAKE_HDAUDIO_CODEC=n,
gcc warns about an unused variable:

sound/soc/intel/skylake/skl.c: In function ‘probe_codec’:
sound/soc/intel/skylake/skl.c:729:18: error: unused variable ‘skl’ [-Werror=unused-variable]
struct skl_dev *skl = bus_to_skl(bus);
^~~
cc1: all warnings being treated as errors

Fixes: 3fd63658caed9 ("ASoC: Intel: Drop hdac_ext usage for codec device creation")
