The TCSR_MUTEX region contains two set of registers: mutex and halt. Add syscon, so the TCSR mutex device (hwspinlock) can use MMIO based method and in the same time share regmap with other devices for the halt regs.

2022-09-13dt-bindings: hwlock: qcom-hwspinlock: add support for MMIO on older SoCsKrzysztof Kozlowski1-3/+12
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.
