As of f98d812e53534 ("power: regulator: Add vin-supply for GPIO and Fixed
regulators")
we must ensure the parent nodes of a regulator are present in DT if
they are described in the vin-supply property
For the am65x reference board the DRAM chips are fed by the 3v3 rail
which is fed by the main 12v rail. Add the bootph properties to these
DT nodes to prevent them from being pruned during the SPL build so we
can enable power to the DRAM chips
