ath11k: Add basic WoW functionalities

Implement basic WoW functionalities such as magic-packet, disconnect
and pattern. The logic is very similar to ath10k.

When WoW is configured, ath11k_core_suspend and ath11k_core_resume
are skipped as WoW configuration and hif suspend/resume are done in
ath11k_wow_op_suspend() and ath11k_wow_op_resume().

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
