wifi: ath12k: switch to name-based reserved memory lookup

Browse source 
The driver currently retrieves reserved memory regions using index-based
lookup, which depends on the ordering of reserved-memory nodes in the
device tree. Since different platforms define these regions in varying
orders and combinations, this approach is not compatible and can result
in incorrect memory region access.

Switch to looking up memory regions by name instead of index so it does
not depend on node order.

Use names already defined in qcom,ipq5332-wifi.yaml, so there are no
backward compatibility issues.

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