CRIS: Rearrange Kconfigs for v10 and v32 to allow compilation without warnings.

- Remove some unneeded configs and add some new ones.
- Merge common config items to common file instead of duplicating them.
- Pull in standard Kconfig.preempt.
- Remove some unneeded Kconfigs for subsystems not (yet) available on CRIS
  (md, scsi, ieee1394, i2o, isdn, telephony, media, pcmcia, pci)
- Rename CRISv32 config items which had different types from CRISv10.
  (ETRAX_LED2G, ETRAX_LED2R, ETRAX_LED3G, ETRAX_LED3R, ETRAX_I2C_DATA_PORT,
  ETRAX_I2C_CLK_PORT)
