Added CPUINFO_INT_CLOCK_MULTIPLIER to support CPU clock multipliers.
Updated all CPU cores to return a CPUINFO_INT_CLOCK_MULTIPLIER of 1. Changed the core to actually respect both CPUINFO_INT_CLOCK_MULTIPLIER and CPUINFO_INT_CLOCK_DIVIDER. Updated a number of drivers to use cpunum_get_clock() instead of Machine->drv->cpu[x].clock. ***** Raw input clock speeds should now be specified for all CPUs in the MACHINE_DRIVER. ***** Removed explicit divisors from all drivers using the following CPU types, which were already specifying non-1 values for CPUINFO_INT_CLOCK_DIVIDER: * COP4x0 * I8039/8048 families * M68(7)05, HD63705 * M6809E * PIC16C5X * TMS32010 * TMS340x0 In a few cases, it appears that the divisor was not being used, so I guessed in those cases whether or not the specified clock speed was raw.
