[ Upstream commit 853735e404244f5496cdb6188c5ed9a0f9627ee6 ]

Only in smp systems the cache policy is setup as write alloc, in
single cpu systems the cache policy is set as writeback and it is
normal memory, so, it should pass the is_normal_memory check in the
share memory registration.

Add the right condition to make it work in no smp systems.

Fixes: cdbcf83d29c1 ("tee: optee: check type of registered shared memory")
