Subject: [RFT PATCH v3 07/16] arm64: dts: qcom: sc7180: split TCSR halt regs out of mutex

The TCSR halt regs are next to TCSR mutex (in one address block called
TCSR_MUTEX), so before converting the TCSR mutex into device with
address space, we need to split the halt regs to its own syscon device.
