TF-A checks the SMC caller world using is_caller_secure,
is_caller_non_secure and is_caller_realm macros. Until
realm world was introduced it was fine to use a pattern like
if (is_caller_non_secure(flags))
return DENY;
// Handle secure call
secure_operation();
is_caller_non_secure would be false for a realm caller, so this pattern
treats this like a secure world caller. This patch fixes
improper use of is_caller_non_secure and is_caller_secure
to handle realm world caller properly.
