Converts from using struct "class_device" to "struct device" making
everything show up properly in /sys/devices/ with symlinks from the
/sys/class directory.

The MMC layer uses the standard work queue for doing card detection. As this
queue is shared with other crucial subsystems, the effects of a long (and
perhaps buggy) detection can cause the system to be unusable. E.g. the
keyboard stops working while the detection routine is running.
The solution is to add a specific mmc work queue to run the detection code in.
This is similar to how other subsystems handle detection (a full kernel
thread is the most common theme).

Leave the overloaded "hotplug" word to susbsystems which are handling
real devices. The driver core does not "plug" anything, it just exports
the state to userspace and generates events.

Only show the scr file in sysfs for SD cards. Previously this was present
for all cards but had a contents of 0 for MMC cards.

There's no point in having the host name duplicated between
the mmc_host structure and the encapsulated class device
structure.

Create a mmc_host class to allow enumeration of MMC host controllers
even though they have no card(s) inserted.
Patch based on work by Pierre Ossman.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
