[PATCH] target/loongarch: Put cpucfg operation before CSR register

On Loongarch, cpucfg is register for cpu feature, some other registers depend on cpucfg feature such as perf CSR registers. Here put cpucfg read/write operations before CSR register, so that KVM knows how many perf CSR registers are valid from pre-set cpucfg feature information. Signed-off-by:
