Revert "PCI: Add ACS quirk for Intel 300 series"
This reverts f154a718e6cc ("PCI: Add ACS quirk for Intel 300 series").
It turns out that erratum "PCH PCIe* Controller Root Port (ACSCTLR) Appear
As Read Only" has been fixed in 300 series chipsets, even though the
datasheet [1] claims otherwise. To make ACS work properly on 300 series
root ports, revert the faulty commit.
