Unfortunatly previous attempt to allow consumer drivers to use COMPILE_TEST option in Kconfig is not enough, because in the past the consumer drivers used 'depends on' Kconfig option but now they are using 'select' Kconfig option which means on non ARM arch'es compilation is triggered. Thus we need to move the ifdefery one level below by touching the private qcom_scm.h header.
