davinci_psc_init is not being called for DM646x EVM, hence davinci_psc_mux is
not defined for DM646x. This is resulting in DM646x board not booting up. I'll
submit a patch to fix this.

The above configurations will hold good only for DM644x and DM355. So they need
to be guarded by cpu_is_davinci_*** macros.
