This looks wrong.  ios->power_mode controls the _card_ power (which is
vmmc-supply), not the signalling power (which is vqmmc-supply):

- vmmc-supply            : phandle to the regulator device tree node, mentioned
                           as the VCC/VDD supply in the eMMC/SD specs.

- vqmmc-supply           : phandle to the regulator device tree node, mentioned
                           as the VCCQ/VDD_IO supply in the eMMC/SD specs.
