intel/skylake: Fix uninitialized variable warning

I don't think the warning is valid, because we already verify
that num_channels is 2 or 4 as soon as we enter the function.
Adding the default case makes the compiler happy.

Fixes warning:
src/soc/intel/skylake/nhlt/dmic.c: In function 'nhlt_soc_add_dmic_array':
src/soc/intel/skylake/nhlt/dmic.c:100:2: error: 'formats' may be used
uninitialized in this function [-Werror=maybe-uninitialized]
return nhlt_endpoint_add_formats(endp, formats, num_formats);
