FUI: Fill in link_m and link_n values
... 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.
