Provide a fixed regulator or something, perhaps we need a "definitely
does not exist" regulator to help with this. For every board you help
with a sequencing bodge you're probably going to break another that
needs different sequencing; for that matter it's not like GPIO
controlled regulators are exclusively used for MMC, or that MMC
exclusively uses GPIO - doing this for only one regulator is a bit of a
red flag.
