Now that we have converted all x86 boards to use driver model timer, remove these legacy timer codes in the tsc driver. Note this also removes the TSC_CALIBRATION_BYPASS Kconfig option, as it is not needed with driver model. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
