The Inter-Thread Communication Unit (ITU, introduced in commit
34fa7e83e11) is part of the Coherent Processing System (CPS),
as describe in commit 408294352ad:

    Make ITU available in the system if CPU supports multithreading
    and is part of CPS.

Replate the CONFIG_MIPS_ITU variable by the CONFIG_MIPS_CPS one.

Philippe, may I ask you to drop this patch in the next version of this
series? The reason is that I want to keep configuration flexibility to
have systems with CPS that doesn't have ITU.

Thanks in advance,
Aleksandar
