Patch from Russell King <rmk@arm.linux.org.uk>

  Remove the dependence of the PCMCIA layer on CONFIG_ISA - introduce
  CONFIG_PCMCIA_PROBE to determine whether we need the resource
  handling code.  This prevents oopsen on SA11x0 and similar platforms
  which use statically mapped, non-windowed sockets.
