Patch to 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.
