It doesn't look to me like there's really a bus here. Perhaps just leave
out that top-level hsio-p2u node? If you only want to somehow organize
these, perhaps a better way would be to add a comment.
Or: the address map lists something called PIPE2UPHY_XBAR at addresses
0x03e00000-0x03e0ffff. Perhaps that really ought to be the "bus" in this
case?
Also, please leave a blank linke between the properties and the nodes
for readability.

It's not clear to me why NVHS PHYs are listed as a separate bus. Also,
these really should be sorted by unit-address. If that means that HSIO
and NVHS PHYs are mixed, so be it. We can use comments to highlight
which PHYs are of which type. Or perhaps we really should be using
different compatible strings for them?
Same comments on the below as for the bindings earlier.
