[PATCH v6 0/3] eDP Data Override

[Suraj Kandpal]

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.

--v2
-Optimize looping

--v3
-Break 2nd patch to two parts
-Rename intel bios parse function
-Create seprate function for setting rates

-v5
-Fix VBT definition
-Rename intel bios function
-Make the function only return mask
-Protect against broken VBT

--v5
-Fix function naming
-Define macro for num of rates

--v6
-check broken vbt inside the reject rate function itself
-no need to use hweight
