The ARM allmodconfig build broke with the addition of the SMD rpmsg
driver that conflicts with the driver its replaces:
WARNING: drivers/soc/qcom/smd: 'qcom_smd_register_edge' exported twice. Previous export was in drivers/rpmsg/qcom_smd.ko
WARNING: drivers/soc/qcom/smd: 'qcom_smd_unregister_edge' exported twice. Previous export was in drivers/rpmsg/qcom_smd.ko
There is already a dependency that is meant to avoid the broken
configuration, but that only prevents the case where at least
one of the two are built-in, but not if both are modules.
This changes the dependency to "=n", to ensure that the new driver
can only be enabled if the other one is completely disabled.
