From a high level view, independently of TMIO/SDHI...

... it is always a good practice to enable irqs only when the device is
fully set up. From a glimpse, this seems to be the case here as well.

It needs serious testing, though. SDHI is a complex, organically grown
mass of code. There might be subtle side effects. It should still be
worth it IMO. I can put it on my todo list, but no promises...
