LoongArch: KVM: Move kvm_iocsr tracepoint out of generic code

The tracepoint kvm_iocsr is only used by the loongarch architecture. As
trace events can take up to 5K of memory, move this tracepoint into the
LoongArch specific tracing file so that it doesn't waste memory for all
other architectures.
