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.

Thanks for the pointer! That approach is fine too, but i was expecting
a re-send and then later completely forgot about it. I have a slight
preference towards my patch, because it is more compact, but i can also
revive Vinod's patch if you think that it would be a better pattern to
follow in the long term.

BR,
Georgi
