KVM: arm64: Add new HiSi CPU type to support DVMBM 

virt inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/IBTXY2



------------------------------------------------------------------------

Add new HiSi CPU type HIP12 for supporting DVMBM.
Function kvm_get_pg_cfg() is used to get configuration
for translating logic cluster id to physical cluster id
which is not needed by hip12, so skip it for hip12.
