... based on the EDID detailed timing values for
pixel_clock and link_clock.
Two undocumented registers 0x6f040 and 0x6f044 correspond to link_m and link_n
respectively. Other two undocumented registers 0x6f030 and 0x6f034 correspond
to data_m and data_n respectively.
Calculations are based on the intel_link_compute_m_n from linux kernel.
Currently, the value for 0x6f030 does not come up right with our calculations.
Hence, set to hard-coded value.

Removed two unnecessary register sets, and did the power well a bit
more correctly. Also, added a register definition include file so we can
used constants instead of magic numbers.
We also set registers to common initialized values that are
needed for FUI, VBIOS, and kernel. This set of registers
appears to be an absolute bare minimum. Since we're hoping to use
FUI for all chipsets from this one forward, we unconditionally do the
setting here.
