The host must be kept active to be able to serve SDIO IRQs, thus let's
prevent it from going inactive while SDIO IRQ is enabled.

At system PM suspend, the tmio core accessed the internal registers of
the controller without first moving the device into active state. This
caused a lock-up in system PM suspend phase.
The reason for the register access were masking of IRQs. Since that is
managed via the runtime PM suspend
Move code for bus_width modification, out of the -set_ios() callback
and into a separate function, to simplify code.

This patchset fixup the PM support for tmio and the tmio hosts.
Some re-structuring of the code was also necessary to accomplish the above.
A few of these patches has been posted earlier, but at that time I couldn't get
help in testing them on hardware. Let's give this a second try now.

It's possible that mmc_of_parse() could return errors (possibly in
some future version it might return -EPROBE_DEFER even). Let's pass
those errors back.
