google/chromeec: Add command to control USB PD role

Normally firmware should have no business messing with the USB PD role
    (source/sink/whatever) in the EC. But, as so often happens, ugly issues
    crop up that require weird work-arounds, and before you know it you need
    to do this for some reason that only makes sense in context. I do now,
    so add this function to send the necessary host command in the simplest
    possible fashion.

BRANCH=gru
    BUG=chrome-os-partner:59346
    TEST=Used it in a follow-up patch.
