Add -Wno-override-init to the build flags for sys_regs.c,
handle_exit.c, and switch.c to fix warnings like the following:

arch/arm64/kvm/hyp/vhe/switch.c:271:43: warning: initialized field overwritten [-Woverride-init]
  271 |         [ESR_ELx_EC_CP15_32]            = kvm_hyp_handle_cp15_32,
      |
