PPC: fix sregs usage on booke
When compiling qemu with kvm support on BookE PPC machines, I get
the following error:
cc1: warnings being treated as errors
/tmp/qemu/target-ppc/kvm.c: In function 'kvm_arch_get_registers':
/tmp/qemu/target-ppc/kvm.c:188: error: unused variable 'sregs'
This is due to overly ambitious #ifdef'ery introduced in 90dc88.
Fix it by keeping code that doesn't depend on new headers alive
for the compiler, but never executed due to failing capability
checks.
