Subject: [RFT PATCH 10/14] arm64: dts: qcom: sdm845: split TCSR halt regs out of mutex

The TCSR halt regs are next to 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.  This also describes more accurately the devices
and their IO address space.
