From: Heiko Carstens <h...@linux.ibm.com>

Qemu's SCLP implementation incorrectly reports that it supports CPU
reconfiguration. If a guest issues a CPU reconfiguration request it
is rejected as invalid command.

Fix the SCLP_HAS_CPU_INFO mask, and remove the unused
SCLP_CMDW_CONFIGURE_CPU and SCLP_CMDW_DECONFIGURE_CPU defines.
