[S390] cio: Add chsc subchannel driver.
This patch adds a driver for subchannels of type chsc.
A device /dev/chsc is created which may be used to issue ioctls to:
- obtain information about the machine's I/O configuration
- dynamically change the machine's I/O configuration via
asynchronous chsc commands
