dt-bindings: hwlock: qcom-hwspinlock: add support for MMIO on older SoCs
Older Qualcomm SoCs have TCSR mutex registers with 0x80 stride, instead
of 0x1000. Add dedicated compatibles for such case. Unfortunately the
binding started using a generic "qcom,tcsr-mutex" compatible without
specifying the SoC part, thus it looks now quite inconsistent.
