arm: armv8: invalidate dcache entries on dcache_enable
In dcache_enable, currently the dcache entries are only invalidated when
the MMU is not enabled. This causes issues when dcache_enable is called
with the MMU already configured, in such cases the existing dcache
entries are not flushed which might result in un-expected behavior.
This patch invalidates the cache entries on every call of dcache_enable
before enabling dcache (by setting CR_C). This makes dcache_enable
behave similar to icache_enable as well.
