KVM/arm64 fixes for 6.14, take #1

Browse source 
- Correctly clean the BSS to the PoC before allowing EL2 to access it
   on nVHE/hVHE/protected configurations
 
 - Propagate ownership of debug registers in protected mode after
   the rework that landed in 6.14-rc1
 
 - Stop pretending that we can run the protected mode without a GICv3
   being present on the host
 
 - Fix a use-after-free situation that can occur if a vcpu fails to
   initialise the NV shadow S2 MMU contexts
 
 - Always evaluate the need to arm a background timer for fully emulated
   guest timers
 
 - Fix the emulation of EL1 timers in the absence of FEAT_ECV
 
 - Correctly handle the EL2 virtual timer, specially when HCR_EL2.E2H==0
