Currently, Ath12k driver only supports WiFi devices that are based on PCI bus. New Ath12k device IPQ5332 is based on AHB bus. Hence, add Ath12k AHB support for IPQ5332. IPQ5332 is IEEE802.11be 2 GHz 2x2 Wifi device. To bring-up IPQ5332 device: - Add hardware parameters for IPQ5332. - CE and CMEM register address space in IPQ5332 is separate from WCSS register space. Hence, add logic to remap CE and CMEM register address. - Add support for fixed QMI firmware memory for IPQ5332. - Support userPD handling for WCSS secure PIL driver to enable ath12k AHB support.
