[PATCH] ath10k: Fixed "Failed to wake target" QCA6174

[liupold]

There is a issue with card about waking up during boot and from suspend
the only way to prevent it (is seems) by making pci_ps = false,
on Acer Swift 3 (ryzen 2500u).

Can you provide dmesg output when this problem happens? Was QCA6174
installed to Swift 3 by default at the factory or did you install it
afterwards on your own?

Is 'liupold' your full legal name?

This increases power consumption for all QCA6174 devices so I'm not
eager to do this.
