[PATCH 03/40] sim/aarch64: Remove unused functions

[Tsukasa OI <research_trasio@irq.a4lg.com>]

Clang generates a warning if there is a unused static function
("-Wunused-function").  On the default configuration, it causes a build
failure (unless "--disable-werror" is specified).

This commit removes unused functions from the AArch64 simulator.
