PCI/ASPM: Allow ASPM on links to PCIe-to-PCI/PCI-X Bridges

PCI/ASPM: Allow ASPM on links to PCIe-to-PCI/PCI-X Bridges

7d715a6c1ae5 ("PCI: add PCI Express ASPM support") added the ability for
Linux to enable ASPM, but for some undocumented reason, it didn't enable
ASPM on links where the downstream component is a PCIe-to-PCI/PCI-X Bridge.

Remove this exclusion so we can enable ASPM on these links.

The Dell OptiPlex 7080 mentioned in the bugzilla has a TI XIO2001
PCIe-to-PCI Bridge. Enabling ASPM on the link leading to it allows the
Intel SoC to enter deeper Package C-states, which is a significant power
savings.

PCI/ASPM: Reduce severity of common clock config message

When the UEFI/BIOS or bootloader has not initialised a PCIe device we would
get the following message:

PCI/ASPM: Reduce severity of common clock config message

When the UEFI/BIOS or bootloader has not initialised a PCIe device we would
get the following message:

kern.warning: pci 0000:00:01.0: ASPM: current common clock configuration is broken, reconfiguring

"warning" and "broken" are slightly misleading. On an embedded system it is
quite possible for the bootloader to avoid configuring PCIe devices if they
are not needed.

Downgrade the message to pci_info() and change "broken" to "inconsistent"
since we fix up the inconsistency in the code immediately following the
message (and emit an error if that fails).

In pcie_config_aspm_l1ss(), we cleared the wrong bits when enabling ASPM L1

cleared the Link Activation Interrupt Enable bit (PCI_L1SS_CAP_L1_PM_SS,

Clear the L1.x enable bits before writing the new L1.x configuration.
