I would suggest working around this in arch/sparc/ instead
of every driver that uses 'select PM', perhaps something like

--- a/arch/sparc/Kconfig
+++ b/arch/sparc/Kconfig
@@ -283,7 +283,7 @@ config ARCH_FORCE_MAX_ORDER
          This config option is actually maximum order plus one. For example,
          a value of 13 means that the largest free memory block is 2^12 pages.
 
-if SPARC64
+if SPARC64 || COMPILE_TEST
 source "kernel/power/Kconfig"
 endif
 
The issue does not happen anywhere else, as it's fine if
kernel/power/Kconfig is not included at all. I'm also not too
worried about random sparc32 configs since it's pretty much impossible
to build a sparc32 allmodconfig or randconfig, with all the other
bugs that runs into.
