PCI/ASPM: Move pci_save_ltr_state() to aspm.c
Even when CONFIG_PCIEASPM is not set, we save and restore the LTR
Capability so that if ASPM L1.2 and LTR were configured by the platform,
ASPM L1.2 will still work after suspend/resume, when that platform
configuration may be lost. See dbbfadf23190 ("PCI/ASPM: Save LTR Capability
for suspend/resume").
Since ASPM L1.2 depends on the LTR Capability, move the save/restore code
to the part of aspm.c that is always compiled regardless of
CONFIG_PCIEASPM. No functional change intended.
