Subject: [PATCH v8 01/10] firmware: qcom_scm: Fix to allow COMPILE_TEST-ing
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.
