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. # # Fixes: 628daa8d5abf
