Most of the timer-calibration methods are not needed on recent Intel CPUs and just increase code size. Add an option to use the known-good way to get the clock frequency in TPL. Size reduction is about 700 bytes.
Note that version 1 of this commit caused bootstage to crash since the CPU was not identified. This is corrected by changes previously applied to make sure that the CPU is identified before spl_init() is called, such as
