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
