x86/intel/quark: Run IMR self-test on IMR capble hw only

Browse source 
Automated testing with LKP shows IMR self test code running and
printing error messages on QEMU hardware lacking IMR support.

Update IMR self-test code to run only when IMR hardware should
be present. Tested on Quark X1000 and QEMU.
