arm64: dts: qcom: ipq6018: switch TCSR mutex to MMIO

[ Upstream commit f5e303ae

 ]

The TCSR mutex bindings allow device to be described only with address
space (so it uses MMIO, not syscon regmap).  This seems reasonable as
TCSR mutex is actually a dedicated IO address space and it also fixes DT
schema checks:

  qcom/ipq6018-cp01-c1.dtb: hwlock: 'reg' is a required property
  qcom/ipq6018-cp01-c1.dtb: hwlock: 'syscon' does not match any of the regexes: 'pinctrl-[0-9]+'
