ath10k: disable interface pause wow config for integrated chipset
wow pause iface config controls the PCI D0/D3-WOW cases for pcie
bus state. Firmware does not expects WOW_IFACE_PAUSE_ENABLED config
for bus/link that cannot be suspended ex:snoc and does not trigger
common subsystem shutdown.
Disable interface pause wow config for integrated chipset(WCN3990)
for correct WOW configuration in the firmware.
Testing:
Tested on WCN3990 HW.
Tested FW: WLAN.HL.2.0-01192-QCAHLSWMTPLZ-1.
