When the RTC is used on systems without a interrupt line, userspace tools like `hwclock` fall back to a frequent polling loop to synchronize with the edge of the next second. On the BQ32000, this aggressive polling can temporarly lock the register refresh cycle, because the continuous transfers prevent the hardware from updating the buffer. This results in stale data reads or select() timeouts in userspace. This patch introduces a delay before reading the RTC registers in order to provide a sufficient idle time for the hardware to sync with the register buffer.
