[Impact]
On some RKL platforms, the built-in display shows nothing on the screen.

[Fix]
Below commit from Intel fix the issue.
https://patchwork.freedesktop.org/patch/398145/?series=83154&rev=3

[Test]
Verified on the RKL platforms.

[Regression Potential]
Low, the new DDC pin map is created for RKL platform only, should lead to
no regression.
