dt-bindings: spmi: split out common QCOM SPMI PMIC arbiter properties

Split out the common SPMI PMIC arbiter properties for QCOM devices into a
separate file so that it can be included as a reference for devices
using them. This will be needed for the upcoming PMIC v8 arbiter
support patch, as the v8 arbiter also uses these common properties.
