ASoC: ssm2518: Use a signed return type for ssm2518_lookup_mcs()

Browse Source 
The return type "unsigned int" was used by the ssm2518_lookup_mcs()
function even though it will eventually return a negative error code.
Improve this implementation detail by deletion of the type modifier then.

This issue was detected by using the Coccinelle software.
