Aren't these three properties of the board?

I wrote it wrong in cover-letter, it's ipq6018, not ipq8074.

Disable it because not all devices have eMMC or MicroSD connected.
I enabled it on the dts of the device and tested it on my ipq6000.

These are just general properties.

Thanks,

? What is a general property? I repeat my question - these do not look
SoC specific, but board.

Best regards,

Sorry, I understood it wrong. I will remove the 1.8v properties
in the next patch.

Thanks,
