Subject: Major PCMCIA Cleanup to make code better readable and maintainable.
 Notes: - Board-dependend code for RPXLITE and RPXCLASSIC-based boards  
 placed to the drivers/rpx_pmcia.c file to avoid duplication.   Same for
 TQM8xx-based boards (drivers/tqm8xx_pmcia.c). - drivers/i82365.c has been
 split into two parts located at   board/atc/ti113x.c and
 board/cpc45/pd67290.c (ATC and CPC45 are   the only boards using
 CONFIG_82365). - Changes were tested for clean build and *very* *few* boards.
