s390-bios: Support for running format-0/1 channel programs
Introduce a library function for executing format-0 and format-1
channel programs and waiting for their completion before continuing
execution.
Add cu_type() to channel io library. This will be used to query control
unit type which is used to determine if we are booting a virtio device or a
real dasd device.
