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.

bool "Preemptible Kernel"

help
This option reduces the latency of the kernel when reacting to
real-time or interactive events by allowing a low priority process to
be preempted even if it is in kernel mode executing a system call.
This allows applications to run more reliably even when the system is
under load.
Enable module allocation with kmalloc instead of vmalloc.
