timer: riscv_aclint_timer: add timer_get_boot_us for BOOTSTAGE timer_get_boot_us function is required to record the boot stages as us-based timestamp. To get a micro-second time from a timer tick, this converts the formula like below to avoid zero result of (tick / rate) part. From: time(us) = (tick / rate) * 1000000 To : time(us) = (tick * 1000) / (rate / 1000) Signed-off-by: Chanho Park <chanho61.park@samsung.com> Reviewed-by: Leo Yu-Chi Liang <ycliang@andestech.com>
