platform/x86/intel/ifs: Add IFS sysfs interface
Implement sysfs interface to trigger ifs test for a specific cpu.
Additional interfaces related to checking the status of the
scan test and seeing the version of the loaded IFS binary
are also added.
The basic usage is as below.
- To start test, for example on cpu5:
echo 5 > /sys/devices/platform/intel_ifs/run_test
- To see the status of the last test
cat /sys/devices/platform/intel_ifs/status
- To see the version of the loaded scan binary
cat /sys/devices/platform/intel_ifs/image_version
