x86: Avoid timer-clock overflow When the clock speed is above about 4GHz, e.g. on modern PC hardware, the timer overflows, resulting in a much lower frequency than expected. Deal with this by capping the clock speed. It would be possible to move to a 64-bit value for the clock, but that is a pain to deal with. A better approach might be to express the clock in MHz but that is left for later consideration. Signed-off-by: Simon Glass <sjg@chromium.org>
