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().

I don't think you can call this if you want to support bootstage, since driver model may not be inited.
if (!ret) {/* The timer is available */rate = timer_get_rate(gd->timer);timer_get_count(gd->timer, &ticks);} else {return 0;}us = (ticks * 1000) / rate;return us;+}
