System: Push boot_cpu_frequency down into the subclasses that actually use it.
This parameter depends on a number of coincidences to work properly. First, there must be an array assigned to system called "cpu" even though there's no parameter called that. Second, the items in the "cpu" array have to have a "clock" parameter which has a "frequency" member. This is true of the normal CPUs, but isn't true of the memory tester CPUs. This happened to work before because the memory tester CPUs were only used in SE mode where this parameter was being excluded. Since everything is being pulled into a common binary, this won't work any more. Since the boot_cpu_frequency parameter is only used by Alpha's Linux System object (and Mips's through copy and paste), the definition of that parameter is moved down to those objects specifically.
