s390/ap: use static qci information
Since qci is available on most of the current machines, move away from
the dynamic buffers for qci information and store it instead in a
statically defined buffer.
The new flags member in struct ap_config_info is now used as an
indicator, if qci is available in the system (at least one of these
bits is set).
