Since commita72178cfe8("net/smc: Fix dependency of SMC on ISM") you can build the ism code without selecting the SMC network protocol. That leaves some ism functions be reported as unused. Move these functions under the conditional compile with CONFIG_SMC. Also codify the suggestion to also configure the SMC protocol in ism's Kconfig - but with an "imply" rather than a "select" as SMC depends on other config options and allow for a deliberate decision not to build SMC. Also, mention that in ISM's help.
