pcmcia: add pcmcia_loop_config() helper

By calling pcmcia_loop_config(), a pcmcia driver can iterate over all
available configuration options. During a driver's probe() phase, one
doesn't need to use pcmcia_get_{first,next}_tuple, pcmcia_get_tuple_data
and pcmcia_parse_tuple directly in most if not all cases.

 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
