s390x/css: ccw translation infrastructure
Implement a basic infrastructure of handling channel I/O instruction
interception for passed through subchannels:
1. Branch the code path of instruction interception handling by
SubChannel type.
2. For a passed-through subchannel, issue the ORB to kernel to do ccw
translation and perform an I/O operation.
3. Assign different condition code based on the I/O result, or
trigger a program check.
