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.
