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.
    Below log level 5, coreboot logs very little, so set the SeaBIOS log
    level to 0, then increase the default log slowly level from there.

- Update default log levels.
    - 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.
