[PATCH v2 1/8] target/loongarch: Add post init function for kvm mode

[Bibo Mao]

Some features such as LBT and PMU are implemented in kvm mode,
With para-virt features in future, post init function is added
for kvm mode, so that property for these features will be created
in kvm post init function.
