    rambi: switch MCLK from 19.2Mhz to 25Mhz
    
    With following settings
        1.Coreboot 25Mhz
        2.Maxim codec configured with MCLK=25Mhz
        2.I2C 400Khz fixed
        4.Including  Enable/Disable SHDN bit when LRCLK starts/Stops
        5.Removed PLL toggle workaround routine.
    audio playing is smooth before/after S3, no noise when recording so change
    MCLK from 19.2 back to 25Mhz.
    
    BUG=chrome-os-partner:26948
    BRANCH=firmware-rambi-5216
    TEST=test audio play and record on Rambi, works fine.
