my understanding based on odroid-c2_rev0.1_20150930.pdf is that:
- there's a (fixed) hdmi_p5v0 regulator using p5v0 as input
- the hdmi_p5v0 is the hdmi-supply

it doesn't change the functionality of this patch (since both supplies
are fixed regulators anyways)
you are already doing a nice cleanup with this series, so it would be
a shame to take a shortcut here
