KVM: arm64: Symbolize the nVHE HYP addresses
Reintroduce the __kvm_nvhe_ symbols in kallsyms, ignoring the local
symbols in this namespace. The local symbols are not informative and
can cause aliasing issues when symbolizing the addresses.
With the necessary symbols now in kallsyms we can symbolize nVHE
addresses using the %p print format specifier:
[ 98.916444][ T426] kvm [426]: nVHE hyp panic at: [<ffffffc0096156fc>] __kvm_nvhe_overflow_stack+0x8/0x34!
