* Enable the PARTITION_WALK property by default
Previously, the new PARTITION_WALK which searches for bootable
partitions after a failure had to be explicitly enabled. Change
the default to be enabled by default. It can be switched off by
setting PARTITION_WALK=0 in the EEPROM config.
* pi5: Fix read for cached copy of PMIC sequencer status
Previously, this was overwritten by the RTC event status.
