[PATCH] pcmcia: add pcmcia_disable_device 

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.

This file details changes in 2.6 which affect PCMCIA card driver authors:
* New release helper (as of 2.6.17)
Instead of calling pcmcia_release_{configuration,io,irq,win}, all that's
necessary now is calling pcmcia_disable_device. As there is no valid
reason left to call pcmcia_release_io and pcmcia_release_irq, they will
be removed soon.
* Unify detach and REMOVAL event code, as well as attach and INSERTION
code (as of 2.6.16)
void (*remove) (struct pcmcia_device *dev);
