ath11k: Add spectral scan support for QCN9074

Populate the below hw parameters as per the QCN9074 support
	1. FFT bin size as two bytes
	2. Maximum FFT bin count as 1024
	3. Summary report pad size as 16
	4. FFT report header length as 24

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1-01492-QCAHKSWPL_SILICONZ-1
