Patrick Talbert 17c9148736 PCI/ASPM: Do not initialize link state when aspm_disabled is set ... Now that ASPM is configured for *all* PCIe devices at boot, a problem is seen with systems that set the FADT NO_ASPM bit. This bit indicates that the OS should not alter the ASPM state, but when pcie_aspm_init_link_state() runs it only checks for !aspm_support_enabled. This misses the ACPI_FADT_NO_ASPM case because that is setting aspm_disabled. The result is systems may hang at boot after 1302fcf; avoidable if they boot with pcie_aspm=off (sets !aspm_support_enabled). Fix this by having aspm_init_link_state() check for either !aspm_support_enabled or acpm_disabled.
