[PATCH ath-next 14/16] wifi: ath11k: update hif and pci ops for QCN6122

[George Moussalem via B4 Relay]

From: George Moussalem <george.moussalem@xxxxxxxxxxx>

Add HIF and PCI ops for QCN6122. QCN6122 by default uses DP window 3.
However, this is configurable, so let's introduce a function to do that and
follow the existing register access code for (hybrid)AHB devices and use
DP window 1.
