[S390] cio: introduce consistent subchannel scanning
Previously, there were multiple subchannel scanning mechanisms
which could potentially conflict with each other. Fix this problem
by moving blacklist and ccw driver triggered scanning to the
existing evaluation method.

[S390] cio: idset use actual number of ssids
The functions idset_sch_new and for_each_subchannel_staged
use different values for the number of subchannel sets. Make
it consistent by changing idset_sch_new to also use the actual
number of subchannel sets.

[S390] cio: introduce css_eval_scheduled
Use css_eval_scheduled to determine if all scheduled subchannel
evaluation is finished. Wait for this value to be 0 in the
channel subsystem init function.

remove asm/bitops.h includes
remove asm/bitops.h includes
including asm/bitops directly may cause compile errors. don't include it
and include linux/bitops instead. next patch will deny including asm header
directly.

[S390] cio: replace subchannel evaluation queue with bitmap
Use a bitmap for indicating which subchannels require evaluation
instead of allocating memory for each evaluation request. This
approach reduces memory consumption during recovery in case of
massive evaluation request occurrence and removes the need for
memory allocation failure handling.
