[PATCH v7 2/5] PCI/ASPM: Always build aspm.c

[Bjorn Helgaas]

From: "David E. Box" <david.e.box@xxxxxxxxxxxxxxx>

Some ASPM-related tasks, such as save and restore of LTR and L1SS
capabilities, still need to be performed when CONFIG_PCIEASPM is not
enabled. To prepare for these changes, wrap the current code in aspm.c
with an #ifdef and always build the file.
