OK.

For Linux to be able to work out how fast its clocks are going, so
that timer ticks come approximately at the right time, it needs to
be able to query the clock control module (CCM).
This is the start of a CCM implementation. It currently knows only about
the MCU, HSP and IPG clocks --- i.e., t
