Per schematic, both PU and SOC regulator are supplied from LTC3676 SW1 via VDDSOC_IN rail, add the PU input. Both VDD1P1, VDD2P5 are supplied from LTC3676 SW2 via VDDHIGH_IN rail, add both inputs.

While no instability or problems are currently observed, the regulators should be fully described in DT and that description should fully match the hardware, else this might lead to unforseen issues later. Fix this.
