Yes. 'hsio-p2u' and 'nvhs-p2u' are not real buses as such. I'll drop both
hsio-p2u and nvhs-p2u nodes and give comments to indicate which P2U brick
a particular P2U block falls in.

Not really. That is different.

I listed NVHS P2Us separately just to distinguish them from HSIO P2Us.
As part of addressing your above comment, I'm going to remove 'hsio-p2u'
and 'nvhs-p2u' nodes and list all P2Us as per their unit address order.
