Subject: [PATCH v2] arm64: dts: qcom: add wifi node for IPQ5332 based RDP441
RDP441 is based on IPQ5332. It has inbuilt AHB bus based IPQ5332 WiFi
device.
Describe and add WiFi node for RDP441. Also, reserve the memory
required by IPQ5332 firmware.

NOTE:
The DT binding changes for this patch has been posted along with the
driver ath12k AHB series.
Link: https://lore.kernel.org/all/20250130043508.1885026-1-quic_rajkbhag@quicinc.com/
v2:
- Dropped 'dt-bindings: net: wireless: describe the ath12k AHB module'.
This DT binding is posted along with the ath12k AHB driver changes.
- Reserved four memory regions required by IPQ5332 ath12k firmware in DTS.
These memory regions are also referenced in the WiFi node.
- Moved 'qcom,smem-states' and 'qcom,smem-states' to the ipq5332.dtsi file.
- Used lowercase hex values for the reg property.
v1: https://lore.kernel.org/all/20250128091012.2574478-1-quic_rajkbhag@quicinc.com/
