vboot: consolidate google_chromeec_early_init() calls

On x86 platforms, google_chromeec_early_init() is used to put the EC
    into RO mode when there's a recovery request. This is to avoid training
    memory multiple times when the recovery request is through an EC host
    event while the EC is running RW code. Under that condition the EC will
    be reset (along with the rest of the system) when the kernel verification
    happens. This leads to an execessively long recovery path because of the
    double reboot performing full memory training each time.

By putting this logic into the verstage program this reduces the
    bootblock size on the skylake boards. Additionally, this provides the
    the correct logic for all future boards since it's not tied to FSP
    nor the mainboard itself. Lastly, this double memory training protection
    works only for platforms which verify starting from bootblock. The
    platforms which don't start verifying until after romstage need to
    have their own calls (such as haswell and baytrail).
