sysctl: add register_sysctl() dummy helper

register_sysctl() has been around for five years with commit
fea478d4 ("sysctl: Add register_sysctl for normal sysctl users") but
now that arm64 started using it, I ran into a compile error:

  arch/arm64/kernel/armv8_deprecated.c: In function 'register_insn_emulation_sysctl':
  arch/arm64/kernel/armv8_deprecated.c:257:2: error: implicit declaration of function 'register_sysctl'

This adds a inline function like we already have for
register_sysctl_paths() and register_sysctl_table().

Fixes: 38b9aeb3 ("arm64: Port deprecated instruction emulation to new sysctl interface")
