[PATCH 18/22] target/s390x: Call s390_cpu_realize_sysemu from s390_realize_cpu_model

[Philippe Mathieu-Daudé]

s390_cpu_realize_sysemu() runs some checks for the TCG accelerator,
previous to creating the vCPU. s390_realize_cpu_model() also does
run some checks for KVM.
Move the sysemu call to s390_realize_cpu_model(). Having a single
call before cpu_exec_realizefn() will allow us to factor a
verify_accel_features() handler out in a pair of commits.

Directly pass a S390CPU* to s390_cpu_realize_sysemu() to simplify.
