ath9k_hw: set pci_express capability true for AR9480
the AR_SREV register does not seems to indicate whether AR9480 is
pci_express capable or not though the other information like macVersion
etc can be obtained properly. this fix is essential as ASPM won't be intialized
and its related driver functionality ath9k_hw_configpcipowersave won't be
called
