When using link rates 2.43 and 6.75 causes a strong noise for WIFI
bands. Its recommended we use 2.7 and 8.1 Gbps instead.
The solution proposed was a static vbt field that provides us with a
mask of rates which need to be skipped in favor of the next higher link
rate.

--v1
-Optimize looping

--v2
-Break 2nd patch to two parts
-Rename intel bios parse function
-Create seprate function for setting rates

-v3
-Fix VBT definition
-Rename intel bios function
-Make the function only return mask
-Protect against broken VBT

--v4
-Fix function naming
-Define macro for num of rates
