ath10k: add the PCI PM core suspend/resume ops
The actual PCI suspend/resume in ath10k has been handled in wow.c, but in the case of the device doesn't support remote wakeup, the .hif_suspend() and .hif_resume() will never be handled. ath10k_wow_op_suspend() { if (WARN_ON(!test_bit(ATH10K_FW_FEATURE_WOWLAN_SUPPORT, ar->running_fw->fw_file.fw_features))) { ret = 1; goto exit; } .... ret = ath10k_hif_suspend(ar); } So register the PCI PM core to support the suspend/resume if the device doesn't support remote wakeup.
