[ARM] 2882/1: pxa2xx_sharpsl: Update PCMCIA driver to support variety of new hardware

Patch from Richard Purdie

This patch updates the PCMCIA pxa2xx_sharpsl driver to support multiple scoop
devices by adding a scoop to pcmcia slot mapping structure. It adds platform
support for poodle, is known to work on spitz (which is dual slot) and
should also support collie with a minor amount of further work.
