    braswell: Tristate CFIO 139 and CFIO 140
    
    CFIO 139 and CFIO 140 are consuming ~5 during stanndby. The reason
    for this leakage is internally it is configured to 1K PU. So there
    is leakage of ~2mW in standby. Total impact ~2.5 mw in Srandby.
    
    Configure these CFIOs as tristate for ~5mW power saving at platform
    level.
    
    BRANCH=none
    TEST=PnP Team to verify that the CFIO's are tri-stated.
