aarch64: fix branch target indications in arm64cpuid.pl and keccak1600

Browse Source 
Add missing AARCH64_VALID_CALL_TARGET to armv8_rng_probe(). Also add
these to the functions defined by gen_random(), and note that this Perl
sub prints the assembler out directly, not going via the $code xlate
mechanism (and therefore coming before the include of arm_arch.h). So
fix this too.

In KeccakF1600_int, AARCH64_SIGN_LINK_REGISTER functions as
AARCH64_VALID_CALL_TARGET on BTI-only builds, so it needs to come before
the 'adr' line.
