config: Add a CPU clock command-line option
This patch adds a 'cpu_clock' command-line option and uses the value
to assign clocks to components running at the CPU speed (L1 and L2
including the L2-bus). The configuration scripts are updated
accordingly.
The 'clock' option is left unchanged in this patch as it is still used
by a number of components. In follow-on patches the latter will be
disambiguated further.
