ctr_el0 access is privileged on this platform and fails as an illegal
instruction.
Windows does not offer a way to flush data cache from userspace, and
only FlushInstructionCache is available in Windows API.
The generic implementation of flush_idcache_range uses,
__builtin___clear_cache, which already use the FlushInstructionCache
function. So we rely on that.
