Nicholas Piggin 682e6b4da5 rtc: opal: Fix OPAL RTC driver OPAL_BUSY loops ... The OPAL RTC driver does not sleep in case it gets OPAL_BUSY or OPAL_BUSY_EVENT from firmware, which causes large scheduling latencies, up to 50 seconds have been observed here when RTC stops responding (BMC reboot can do it). Fix this by converting it to the standard form OPAL_BUSY loop that sleeps.
