Fix AT91RM9200 build breakage
The at91_cf driver got out of sync with certain changes in the PCMCIA layer, notably getting rid of some duplication of data ... causing the version merged to kernel.org to fail compiling. This patch gives the at91_cf platform device a new iomem resource, using it so this new pcmcia scheme works. It also cleans up some whitepsace bugs that have accumulated over time (mostly too-long lines).
