I'm not sure I'm buying the idea that we have a powerup driver that's
meaningfully not part of the main device driver.

I am having a bit hard to follow the terminology here. :-) What is a
"powerup driver" and what is a "main device driver" in this context?

Yes, that's mostly what I'm saying as well.  The main device driver is
the driver that will bind to the SDIO device and control it, the powerup
driver is the separate bit of code which will ensure that device is
powered up - calling it a device driver seems a bit of a misnomer to me.
