ANDROID: KVM: arm64: Always resolve nvhe BUGs file and line

ELR virt address is always shared by the hypervisor and then compared
against a host accessible ELF section. Also, Now pKVM prefaults the
entire host stage-2, we are not at risk of triggering a memory abort in
the panic path. There is no need to hide that feature behind
NVHE_EL2_DEBUG anymore.
