So shouldn't there be a documented LDO_VIN1/2 then?

LDO_VINx is HW design layout, so actually it can't be changed by device tree.
LDO_VIN1/LDO_VIN2 supply from VSYS, not regulator, so I think usually
not to show the supply from in device tree.
or I should declare a dummy reference to system power like "*-supply =
<&system_power>;"?

When you say it's from the hardware design do you mean it's fixed by the
silicon or is this something that's fixed in the board?
