There's no build time dependency on EXYNOS_MBOX, but there is on MAILBOX:

ERROR: modpost: "mbox_request_channel"
[drivers/firmware/samsung/acpm-protocol.ko] undefined!
ERROR: modpost: "mbox_free_channel"
[drivers/firmware/samsung/acpm-protocol.ko] undefined!
ERROR: modpost: "mbox_send_message"
[drivers/firmware/samsung/acpm-protocol.ko] undefined!
ERROR: modpost: "mbox_client_txdone"

Will replace the line with "depends on MAILBOX".

Thanks!
