soc: qcom: service-locator: update types in get_service_location()

Browse Source 
Currently, get_service_location() expects "char *" for client
name and service name from clients. Update this to "const char *"
as they're not supposed to be changed by service locator. This
also helps clients to pass a "const char *" when it reads
strings from device tree using of_property_read_string_index().
