csky: Remove unnecessary flush_icache_* implementation
The abiv2 CPUs are all PIPT cache, so there is no need to implement
flush_icache_page function.
The function flush_icache_user_range hasn't been used, so just
remove it.
The function flush_cache_range is not necessary for PIPT cache when
tlb mapping changed.
