intel/skylake: Display ME firmware status before os boot

Browse Source 
Display ME firmware status before os boot. Specifically this
patch reads out the ME hfsts1 and hfsts2 status registers that provide
information about overall ME health before device gets disabled.
This change reused most of the code from bdw me_status implementation.

BUG=chrome-os-partner:47384
BRANCH=glados
TEST=Builds and Boots on FAB4 SKU2/3. Can observe me status table
