    nb/intel/gm45: Fix panel-power-sequence clock divisor
    
    We kept this value at it's default on the native graphics init path.
    Maybe the Video BIOS path, too, I don't know if the VBIOS sets it.
    
    The panel power sequencer uses the core display clock (CDCLK). It's
    based on the HPLLVCO and a frequency selection we made during raminit.
    The value written is the (actual divisor/2)-1 for a 100us timer.
    
    v2: Fix unaligned mmio access inherited from Linux.
    
    v3: Use MCHBAR8() instead. Also, the unaligned access might have
        worked after all.
