    imgtec/pistachio: DDR reads return to controller with no bubbles
    
    When the PHY is compiled to run in HDR(half data rate),
    then either NOBUB or FXDAT must be set to 1 in the DDR
    system general configuration register. NOBUB specifies
    that reads should be returned to the controller with
    no bubbles and this is felt preferable to the fixed
    latency option (FXDAT). Both of them inrease read
    latency.
    
    BRANCH=none
    BUG=chrome-os-partner:37087
    TEST=tested on Pistachio bring up board -> DDR initialized
         properly and ramstage executed correctly
