char: group dev configs togther 



Group /dev/{mem,kmem,nvram,raw,port} driver configs together.
This also means that tty configs are now grouped together instead
of being split up.

This just moves Kconfig lines around. There are no other changes.

	  This memory is conventionally called "NVRAM" on PowerPC machines,

	  "CMOS RAM" on PCs, "NVRAM" on Ataris and "PRAM" on Macintoshes.

	  module will be called nvram.
