portable: also fix IAR ARM_CM33 non-secure portasm.s stray URL

The CM33 non-secure portasm.s exists at two identical paths, and the
previous commit only covered the ARMv8M one. The legacy path
portable/IAR/ARM_CM33/non_secure/portasm.s is the file referenced in
#1480, so it must be fixed as well - otherwise the reported build
failure remains.
