Thanks to report this issue. :)
The root cause is that the test config doesn't enable
CONFIG_CPU_SUP_AMD.

How about below fix:

---
diff --git a/drivers/hwmon/Kconfig b/drivers/hwmon/Kconfig
index 796569ee..603eadd 100644
--- a/drivers/hwmon/Kconfig
+++ b/drivers/hwmon/Kconfig
@@ -288,7 +288,7 @@ config SENSORS_K10TEMP
 
 config SENSORS_FAM15H_POWER
 	tristate "AMD Family 15h processor power"
-	depends on X86 && PCI
+	depends on X86 && PCI && CPU_SUP_AMD
 	help
 	  If you say yes here you get support for processor power
 	  information of your AMD family 15h CPU.

Thanks,
Rui
