[PATCH] bsps/aarch64/cache: Clean up unused fuctions

[Kinsey Moore]

When the CPU_CACHE_SUPPORT_PROVIDES_RANGE_FUNCTIONS definition was added
to AArch64 cache management, it obsoleted the *_1_data/instruction_line
functions. These have been removed since they are no longer referenced.
The AArch64_instruction_cache_inner_shareable_invalidate_all function is
only used when RTEMS_SMP is defined, so only define it in that
circumstance.
