wifi: ath12k: add AHB platform descriptor support

Browse source 
AHB-based platforms associate each device with a userPD ID that determines
the firmware name and Peripheral Authentication Service ID (PASID) used
during firmware authentication.

Current implementation does not support platforms with multiple devices
sharing the same compatible string but using different userPD IDs.
As a result, the driver cannot uniquely identify each device for firmware
selection and authentication.

Add an AHB platform descriptor to store device-specific configuration.
Implement userPD ID resolution by matching device tree reg properties, with
node name matching as a fallback. Centralize platform configuration to
simplify the probe path by removing hardware-specific conditionals.

Tested-on: IPQ5332 hw1.0 AHB WLAN.WBE.1.6-01275-QCAHKSWPL_SILICONZ-1
