config: Add a system clock command-line option
This patch adds a 'sys_clock' command-line option and use it to assign clocks to the system during instantiation. As part of this change, the default clock in the System class is removed and whenever a system is instantiated a system clock value must be set. A default value is provided for the command-line option. The configs and tests are updated accordingly.
