Since commit aed65af1cc2f ("drivers: make device_type const"), the driver
core can properly handle constant struct device_type. Move the sdio_type,
sd_type and mmc_type variables to be constant structures as well, placing
it into read-only memory which can not be modified at runtime.

sprintf() (still used in the MMC core for the sysfs output) is vulnerable
to the buffer overflow. Use the new-fangled sysfs_emit() instead.

A significant amount of functions and other definitions are available
through the public mmc card.h header file. Let's slim down this public mmc
interface, as to prevent users from abusing it, by moving some of the
functions/definitions to private mmc header files.
This change concentrates on moving the functions into private mmc headers,
following changes may continue with additional clean-ups.

This is the first step in cleaning up the private mmc header files. In this
change we makes sure each header file builds standalone, as that helps to
resolve dependencies.
While changing this, it also seems reasonable to stop including other
headers from inside a header itself which it don't depend upon.
Additionally, in some cases such dependencies are better resolved by
forward declaring the needed struct.

Conversion from struct device to struct mmc_card is used more than in one
place. Due to this it's better to have public macro for such thing.

Suppressing uevents turned out to be a bad idea as it screws up the
order of events, making user space very confused. Change the system to
use sysfs groups instead.
This is a regression that, for some odd reason, has gone unnoticed for
some time. It confuses hal so that the block devices (which have the
mmc device as a parent) are not registered. End result being that
desktop magic when cards are inserted won't work.

Move bus operations to its own file for the sake of clarity. Also
delegate sysfs attributes to bus handlers in preparation for other
more exotic types.
