state: make first boot less verbose
First boot with uninitialized state is needlessly verbose:
state: New state registered 'state'
state: Detected old on-storage format
ERROR: state: Error, invalid header crc in raw format, calculated 0x7bd5c66f, found 0x00000000
state: Ignoring broken bucket 0@0x00000000...
state: Detected old on-storage format
ERROR: state: Error, invalid header crc in raw format, calculated 0x7bd5c66f, found 0x00000000
state: Ignoring broken bucket 1@0x00040000...
state: Detected old on-storage format
ERROR: state: Error, invalid header crc in raw format, calculated 0x7bd5c66f, found 0x00000000
state: Ignoring broken bucket 2@0x00080000...
ERROR: state: Failed to find any valid state copy in any bucket
ERROR: state: Failed to read state with format raw, -2
This has confused barebox-state novices more than once. Let's handle
the zeroed state case specially and reduce output in that case, so
it now looks like this:
state: New state registered 'state'
state: Detected old on-storage format
state: Detected old on-storage format
state: Detected old on-storage format
state state.of: Fresh state detected, continuing with defaults
This is only the output when CRC is zero (hinting at zeroed state
partition). If crc != zero, then output is a little more verbose than
before:
state: New state registered 'state'
state: Detected old on-storage format
ERROR: state: init error: Invalid argument: header crc in raw format, calculated 0x7bd5c66f, found 0x00000000
