dt-bindings: interconnect: qcom: Do not require reg for sc8180x virt NoCs

The virtual interconnect providers do not have their own IO address space,
but this is not documented in the DT schema and the following warnings are
reported by dtbs_check:

sc8180x-lenovo-flex-5g.dtb: interconnect-camnoc-virt: 'reg' is a required property
sc8180x-lenovo-flex-5g.dtb: interconnect-mc-virt: 'reg' is a required property
sc8180x-lenovo-flex-5g.dtb: interconnect-qup-virt: 'reg' is a required property
sc8180x-primus.dtb: interconnect-camnoc-virt: 'reg' is a required property
sc8180x-primus.dtb: interconnect-mc-virt: 'reg' is a required property
sc8180x-primus.dtb: interconnect-qup-virt: 'reg' is a required property

Fix this by adding them to the list of compatibles that do not require
the reg property.
