SMEM uses lock index 3 of the TCSR Mutex hwlock for allocations
in SMEM region shared by the Host and FW.
Fix the SMEM hwlock index to 3 for IPQ5332, IPQ6018, IPQ8074 and IPQ9574.

Please make it a separate patch for each one. Somebody trying to revert
this in the future will have to potentially resolve 4 conflicts in this
current form.
