Currently this timer driver provides timer_get_boot_us() to support the BOOTSTAGE functionality. This patch adds the timer_early functions so that the "normal" timer functions can be used, when CONFIG_TIMER_EARLY is enabled.
timer_get_boot_us() will get removed in a follow-up patch, once the BOOTSTAGE interface is migrated to timer_get_us().
