qualcommax: IPQ807x: ZyXEL NBG7815: Fix random Wifi MAC
For this particualar device we get random MAC's for Wifi on each (re-)boot.
This is because art partition/pre caldata do not contain valid MAC addresses.

As we have now a new/better approach with ath11k_patch_mac we can use it for
this device too.

I'm using this approach for like two weeks and its working flawlessly.
