PCI/ASPM: Simplify Clock Power Management setting
Update the Link Control Enable Clock Power Management bit the same way we update the ASPM Control bits, with a single call of pcie_capability_clear_and_set_word(). No functional change; this just makes both paths use the same style. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
