ath11k: add qcn9074 pci device support

Browse source 
QCN9074 is PCI based 11ax radio.
	- has 2G/5G/6G variants.
	- has NSS 2x2 and 4x4 variants.

QCN9074 uses 45MB of HOST DDR memory, target requests host memory in
segments, each segment is of 2MB size and is physcial contiguous and
use static window configuration.

Currently there are still two issues with QCN9074, see below. So we don't add
QCN9074 PCI id yet to make sure the driver is loaded. The id will be added only
after the issues are fixed.

Issue 1:
 ath11k_pci 0000:06:00.0: qmi failed memory request, err = -110
 ath11k_pci 0000:06:00.0: qmi failed to respond fw mem req:-110

Issue 2:
 ath11k_pci 0000:06:00.0: firmware crashed: MHI_CB_SYS_ERROR
 ath11k_pci 0000:06:00.0: qmi failed set mode request, mode: 0, err = -110
 ath11k_pci 0000:06:00.0: qmi failed to send wlan fw mode:-110

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1.r2-00012-QCAHKSWPL_SILICONZ-1
