broadwell: Read and save HSIO version from ME in romstage

Hardware / Coreboot - Duncan Laurie [chromium.org] - 27 March 2015 00:25 UTC

This can be used to know if HSIO registers need updating in ramstage but it is not possible to query the ME for HSIO version after sending the DRAM-init-done message.

BUG=chrome-os-partner:28234 BRANCH=samus TEST=build and boot on samus, check for HSIO version messages in log
