Instead of the two status values struct pcmcia_device->p_state and state,
use descriptive bitfields. Most value-checking in drivers was invalid, as
the core now only calls the ->remove() (a.k.a. detach) function in case the
attachement _and_ configuration was successful.

Most of the driver initialization isn't done in the .probe function, but in
the internal _config() functions. Make them return a value, so that .probe
can properly report whether the probing of the device succeeded or not.

Embed dev_link_t into struct pcmcia_device(), as they basically address the
same entity. The actual contents of dev_link_t will be cleaned up step by step.

In all but one case, the suspend and resume functions of PCMCIA drivers
contain mostly of calls to pcmcia_release_configuration() and
pcmcia_request_configuration(). Therefore, move this code out of the
drivers and into the core.

pcmcia_disable_device(struct pcmcia_device *p_dev) performs the necessary
cleanups upon device or driver removal: it calls the appropriate
pcmcia_release_* functions, and can replace (most) of the current drivers'
_release() functions.

Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified
probe() callback. As all in-kernel drivers are changed to this new
callback, there will be no temporary backwards-compatibility. Inside a
probe() function, each driver _must_ set struct pcmcia_device
*p_dev->instance and instance->handle correctly.

With these patches, the basic driver interface for 16-bit PCMCIA drivers
now has the classic four callbacks known also from other buses:

        int (*probe)            (struct pcmcia_device *dev);
        void (*remove)          (struct pcmcia_device *dev);

        int (*suspend)          (struct pcmcia_device *dev);
        int (*resume)           (struct pcmcia_device *dev);

Signed-off-by: NDominik Brodowski <linux@dominikbrodowski.net>

Move the suspend and resume methods out of the event handler, and into
special functions. Also use these functions for pre- and post-reset, as
almost all drivers already do, and the remaining ones can easily be
converted.

Devices driven by ide-cs will appear under /sys/devices instead of the
appropriate PCMCIA device. To fix this I had to extend the hw_regs_t
structure with a 'struct device' field, which allows us to set the
parent link for the appropriate hwif.

Avoid registering PCMCIA CF cards before other IDE stuff. This means the risk

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!
