Is it not enough to set those to status = "disabled"? Kind of strange
that you have to delete those entirely. I guess ideally "hdmi" should
even be disabled by default in the SoC device tree.

regulator-fixed is active-low without "enable-active-high;"
If that's what you want it's probably more clear to write
GPIO_ACTIVE_LOW. Otherwise, perhaps you forgot that property? :)
