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/qcs404-evb-4000.dtb: hwlock: 'reg' is a required property
  qcom/qcs404-evb-4000.dtb: hwlock: 'syscon' does not match any of the regexes: 'pinctrl-[0-9]+'
