ARM: dts: qcom: apq8084: switch TCSR mutex to MMIO

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-apq8084-mtp.dtb: hwlock: 'reg' is a required property
  qcom-apq8084-mtp.dtb: hwlock: 'syscon' does not match any of the regexes: 'pinctrl-[0-9]+'
