From: Sriram R <quic_srirrama@xxxxxxxxxxx>
The Destination ring control register is different
for IPQ5018 when compared to IPQ8074/IPQ6018/QCN9074.
Hence create a new hw ops to fetch the hash ring map
for different device variants. ipq5018 hw ops
is similar to qcn9074 except for this change, so reuse
all the qcn9074 ops for ipq5018.
Tested-on : IPQ5018 hw1.0 AHB WLAN.HK.2.6.0.1-00861-QCAHKSWPL_SILICONZ-1
