Configure the SSC driver so that the CPU is in master mode (CBS_CFS).

Older versions of the sam9g20 driver ran the SSC in master mode, that
might be useful to refer to.  There's normally a clocking diagram in the
manual for the SoC showing the clocking structure with all the dividers
you can configure.
