IPQ6018 has 32 tcsr_mutext hwlock registers of 0x1000 size each.
The compatible string qcom,ipq6018-tcsr-mutex is mapped to
of_msm8226_tcsr_mutex which has 32 locks configured with stride of 0x80
and doesn't match the HW present in IPQ6018.

This series fixes the following:
1. Fix the tcsr_mutex hwlock register size to 0x20000 in ipq6018.dtsi.
2. Remove qcom,ipq6018-tcsr-mutex compatible string for tcsr_mutex in
3. Drop unused qcom,ipq6018-tcsr-mutex compatible string from
qcom_hwspinlock driver and dt-bindings.

Sounds like 20230904063344.4144086-1-quic_viswanat@xxxxxxxxxxx can't
go in without this then?

They can independently go in as the current max size and stride set for
IPQ6018 still has 32 locks and moving the index 3 shouldn't cause any issues.

However, functionally IPQ6018's HW lock is broken and will be fixed once this series goes in.
