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.
- Add ath12k AHB support.

Depends-On: [v6] Add multipd remoteproc support
Link: https://lore.kernel.org/all/20231110091939.3025413-1-quic_mmanikan@quicinc.com/

Note that the dependency patch series - [v6,00/11] Add multipd
remoteproc support, has the below issues:

1. The remoteproc maintainers don't want any userpd code in remoteproc.
   As a result of this, the approach being taken by this series may
   change.

2. Due to latest changes in linux-next/ath ToT, [v6,00/11] Add multipd
   remoteproc support is unable to compile. Below compilation fixes are
   required in the file "drivers/remoteproc/qcom_q6v5_mpd.c":
   - Add "#include <linux/of_platform.h>"
   - Change "static int q6_wcss_remove" to "static void q6_wcss_remove"
     and remove "return 0".

3. The IPQ5332 firmware patch is pointing to ath11k firmware path, but
   IPQ5332 is Ath12k chipset.
   In patch [v6,10/11] arm64: dts: qcom: ipq5332: Add nodes to bringup
   multipd, firmware path should be: ath12k/IPQ5332/hw1.0/
