Maybe we should stub out ioremap() and friends when COMPILE_TEST is enabled to
avoid these linker errors. That's in my opinion better than turning most of the
'depends on COMPILE_TEST' into 'depends on COMPILE_TEST && HAS_IOMEM'. The
issue comes up quite a lot and it is often overlooked when adding a driver that
can be build when COMPILE_TEST is enabled.
