However, it does not add any consumer for this clock. This causes the common clock framework to disable it, preventing RTC time access. Since the RTC's timekeeping clock should always be enabled, regardless of which drivers are loaded, let's mark this clock as critical instead of adding a consumer in the RTC driver.
