While comparing the vendor dts with the one added in v5.11-rc1 I noticed
that the vendor dts specified 3.3 V which matches the SDIO specification.
So fix the sdio regulator to provide (up to) 3.3 V.

hups, sorry, fat fingers. This patch is wrong, I planned to send out a
different patch. Please just discard this one.
Best regards
