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.
