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.
