Actually, thinking more, this should be probably be handled using
"no-1-8-v" property. Reading the comment above SDHCI_QUIRK2_NO_1_8_V, it
is specifically meant for the case when system (board) does not support
1.8V even when host (controller) does. Which is exactly the case with
Beagle x15.

Thanks,
