soc/intel/apollolake: clear up ACPI timer emulation magic constant
The timer emulation works by deriving a frequency based off the Common Timer Copy with a frequency of 19.2MHz. The desired frequency = (19.2MHz * multiplier) >> 32; With that knowledge update the code to let the compiler perform the necessary math based on target frequency.
