typo: "schematics"
according to the schematics there's both:
- VDDIO_AO3V3
- VCC3V3 (which is turned on by VDDIO_AO3V3, see [0])

personally I would call this (along with the node name and alias) DDR3_1V5
odroid-c2_rev0.1_20150930.pdf shows that DDR3_1V5 and DDR_VDDC are
both the same. however, the DDR_VDDC signal name is not used by any
component in the datasheet

odroid-c2_rev0.1_20150930.pdf uses VCC3V3 as supply
