lynxpoint/broadwell: Correct PCH-LP PCIe ASPM check

Lynx Point PCH reference code version 1.9.1 checks bit 29 to detect ASPM
on PCH-LP root port #6, not bit 28. Document 535127 (BDW PCH-LP BS) also
uses bit 29 for root port #6. Correct the bit used in the check, as well
as the surrounding comments.
