SeaBIOS Kconfig: Update logging

The SeaBIOS and coreboot log levels don't really align, so setting the
SeaBIOS log level to the same as coreboot's isn't really what we want.

- Update default log level to use the default SeaBIOS log level.
- Update the current help text to match the new defaults.
- Add help text for what is displayed at various levels.
- Get rid of separate type & prompt lines.
- Add comments for default seabios level & logging disabled
