There is currently no way to disable nVHE ASLR, e.g. for debugging, so the first patch in this series makes it conditional on RANDOMIZE_BASE, same as KASLR. Note that the 'nokaslr' command line flag has no effect here. Second patch unifies the HARDEN_EL2_VECTORS errate for A57 and A72 behind the same Kconfig for simplicity. Happy to make it just depend on RANDOMIZE_BASE if having an option to keep randomization on but hardenning off is preferred.
