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.
