s390/cio: export measurement data for all CMGs
A channel-path's channel-measurement-group value (CMG) determines the
format of associated measurement data and characteristics blocks. Both
blocks are of fixed size and contain a generic and CMG-dependent part.
Currently CIO exports these data blocks via sysfs only for a specific
list of CMGs even though the kernel itself does not interpret
CMG-dependent data.
Change CIO to export measurement data and characteristics for all CMGs.
This enables supporting new CMG data formats in userspace without the
need for kernel changes.
