KVM: arm64: Advertise ID_AA64PFR0_EL1.CSV2/3 to protected VMs
[ Upstream commit e816252 ] The existing pKVM code attempts to advertise CSV2/3 using values initialized to 0, but never set. To advertise CSV2/3 to protected guests, pass the CSV2/3 values to hyp when initializing hyp's view of guests' ID_AA64PFR0_EL1. Similar to non-protected KVM, these are system-wide, rather than per cpu, for simplicity.
