Having multiple loadable modules with the same name cannot work with modprobe, and having both net/qrtr/smd.ko and drivers/soc/qcom/smd.ko results in a (somewhat cryptic) build error: ERROR: "qcom_smd_driver_unregister" [net/qrtr/smd.ko] undefined!

Also, the qrtr driver uses the SMD interface and has a Kconfig dependency, but also allows for compile-testing when SMD is disabled. However, if with QCOM_SMD=m and COMPILE_TEST=y we can end up with QRTR_SMD=y and that fails with a related link error. The changes the dependency so we can still compile-test the driver but not have it built-in if SMD is a module, to avoid running in the broken configuration, and changes the Makefile to provide the driver under a different module name.
